Front-end developers are responsible for web content, so how does it work with this job. They figure out what web pages should look like and how they will function, including the layout of elements on a page (such as text boxes, menus, images). They also design the form(s) that collect information from users before sending it to a web server. Once the data is received by the server-side script or database program, some computing then takes place based on user input and has results sent back to the browser for display. Front-end developers typically build their site's 'look' with technologies such as CSS3 & HTML5/HyperText Markup Language 5. These web developers are expected to have excellent knowledge of HTML5, CSS3, ECMA Script, JavaScript, and other Javascript frameworks.

Requirements for front-end development

Front end web development requires the following technical expertise:

1. Good grasp of HTML5 & CSS3 technologies.

2. Ability to work with Javascript Frameworks like AngularJs/ReactJs/BackboneJS etc.

3. Knowledge about the Bootstrap framework is desirable but not mandatory since its popularity is increasing at a very fast rate.

4. Familiarity with js libraries like jQuery , Nodejs/NPM package manager , Gulp task runner or Grunt task manager will be helpful in long run especially while doing projects involving integration of third parties js libraries.

5. a Basic understanding of server-side technologies including Nodejs, PHP, Mysql, Apache is a plus point as it will help understand how browser-server interaction happens.

6. Understanding cross-browser issues and ways to resolve them.

7. Optionally can learn Angular 2+ or ReactJS / VueJs / EmberJs for future-proofing yourself with the latest frameworks & tools that are popular this year.

8. Good understanding of code versioning tools like Git/Github etc is preferable but not mandatory since major JavaScript framework provides their way of managing versions using NPM(Node Package Manager) packages for front-end dependencies needed by the application/website being built.

9. And if you are passionate about coding it's always good to learn more things at your own pace or by enrolling in further courses for learning new technologies, frameworks, best practices, etc.

Tell me the best way to learn to code?

There are many ways to learn to code from free online courses from Codecademy, Treehouse, Udacity & Pluralsight.

You can also use Youtube videos for learning certain topics in a very practical manner covering majorly the front-end technologies.

Also available is CSS Tricks which covers lots of CSS3 tutorials and has a long list of JavaScript frameworks compared against each other. These sites have one important point in common, they provide an 'interactive' experience by encouraging you to write code at their site itself (or sometimes suggesting some text editors like Atom or sublime which lets you write code snippets on your own) while explaining what exactly is happening under the hood when the code is run.

These sites are good for beginners but, do not expect these to be comprehensive enough for serious front-end web developers that need to build enterprise-level applications with robust front-end architecture and complex UI interactions. So, where should you go from here? An ideal approach would be to start building a simple web page/web application using frameworks like AngularJs or ReactJs and while doing so take care of all issues related to version management. These quickly teach large-scale application development and how javascript frameworks help in achieving the same. After gaining some hands-on experience it's recommended to write a blog post describing your thought process and its implementation during the development of any application/website which will help cement the learning at 3 levels - 1) A great way of learning a new framework is by creating a sample application using it. 2) Writing a step-by-step blog post on how to develop an application with the technology makes you apply the learnings of the framework in real-life situations. 3) In the future, while doing any front-end related work on your existing projects or when applying for a new job this post acts as great reference material.

Front end development roles & responsibilities

In my experience, these are usually divided into 4 tasks:

1. HTML markup and CSS styling - Using appropriate HTML5 elements and writing some basic CSS to give them decent styling that does not look odd on different browsers and devices across multiple resolutions while prioritizing performance over aesthetics, takes up a large part of the front-end development work.

2. Reusable components - Everything on a modern web page/web app is organized into reusable components that have their Javascript, CSS, and UI files which can be called from anywhere across the codebase to be used in any project saving lots of time and effort when developing new projects. In AngularJs these are called directives while ReactJs call them components.

3. Managing JS libraries & dependencies - Since JavaScript frameworks are written by many contributors you need to depend upon 3rd party packages/dependencies which provide certain ready-to-use functionality required to implement specific features. There are multiple ways to manage these dependencies among them being NPM, Bower, etc but if you are using a JS framework then you have to stick to the one it requires. In AngularJs it's NPM and Bower while React works with NPM only.

4. Testing - Web applications must work as intended on all browsers within different devices with those having differing screen resolutions, widely used browser plugins and ad-ons, and with varying network speeds (some users may use an EDGE connection). The best way of making sure your application is working fine across all these instances is by writing automated tests for them alongside developing the application itself. This ensures defects are caught early before they make their way into the production codebase and can be fixed quickly saving lots of time and effort which often gets wasted due to such issues.

How to run your project?

Once you finish the development of your project and get it ready for deployment, you would need to know how to run locally so that you can test it while working on it without any network dependency (for example, while developing an AngularJs app with a back-end running on NodeJS, you should be able to run everything locally without relying upon a remote server).

1. If all dependencies are managed by NPM then use the npm start command which will automatically detect the other necessary files like grunt file etc within your project directory and automatically run the tasks defined in them.

2. If you are using Gulp or Grunt as your task runner then go to http://localhost:9000/build/ where 9001 is the port number on which the server is listening and the path "/build/" is where you should point your local web-server to. In case you are developing a NodeJS project then use this URL instead - http://localhost:8000/build/.

3. If you have written all tasks in separate files then manually go to each file and run that task one by one for a manual debugging session.

How to deploy?

Once your application development gets completed, you need to deploy it on a remote server so that other users can access it from anywhere across the globe without having to download it first from some location. There are multiple ways of deploying code depending upon factors like how critical or bug-free your application is, whether or not it requires constant updates, etc.

1. If you wish to host the application yourself then use the command line tool FTP (Filezilla) to transfer all your files to a web server on your hosting provider or use Githubs' Deploy feature if you are using it for version control purposes.

2. Use system tools like Rsync or SCP in case you have a limited number of files within a project and want to maintain a version history without any third-party intervention.

3. If you are developing an AngularJs app with NodeJS as the back-end server then use either NGINX or Apache to serve static files while forwarding requests from client-side code running in the browser to NodeJS server using the Reverse HTTP Proxy method because modern browsers don't allow Cross-Origin Resource Sharing (CORS) requests to run on localhost.

How to add libraries to Your JavaScript Project?

When working with web applications using JavaScript, you might encounter scenarios where your application needs to use some additional library that is not available in the required version or by default. There are multiple ways in which you can add third-party libraries to an existing project.

1. If the library is hosted on NPM then use command-line tool npm for adding it to your project JS code repository and install it locally within your project directory. With this method, you are free from any dependency issues when upgrading the library.

2. Add a specific file into your JavaScript codebase whose name starts with "vendor" (e.g., my-libs/vendor/jquery) representing third-party code that must be loaded after all other scripts within the HTML page.

3. Create a new directory called "vendor" and place all your third-party scripts into it (e.g., my-libs/vendor). The downside of this approach is that you won't be able to use version control systems like Git with such directories because third-party libraries are supposed to reside inside the vendor/ sub-directory and not in an application-specific one.

How do You manage CSS files?

Even though most modern JavaScript frameworks like AngularJs rely heavily on CSS for styling purposes, it is still considered as a separate entity from the frontend codebase when working with native JavaScript applications or any other frameworks where custom HTML tags are used extensively. Therefore, when developing JS driven web apps, you should keep the following points in mind:

1. All your CSS files must be placed within a single directory (e.g., CSS) and not nested into sub-directories because it is easier to maintain them this way.

2. Place each of your CSS files into separate directories based upon their usage (e.g., vendor/bootstrap/) and make sure that every file's name starts with "vendor-" or "lib-" prefixes to represent third-party code that must be loaded after all other scripts on the HTML page have been executed successfully.

3. If using SASS/LESS as preprocessors then use corresponding plugins for task runners Gulp or Grunt so that source .css files are automatically compiled into .css style sheets based upon the mapping that you've provided in their configuration.

How to include Third-Party Libraries?

Many open-source JavaScript libraries are freely available on the Internet to be used by end developer for developing applications across multiple platforms. However, if you need to use any of them within your development project then it's better to download its source code and place them under an appropriate sub-directory so that they can be accessed via the path defined by the src attribute. Also, note that there is no specific naming convention for third-party files so you cannot simply assume all files to be libraries unless they end with something like ".min.js" denoting compression or ".min.CSS" indicating minification (removal of whitespace and comments). In case you intend to use a specific version of a library then it's better to name the file accordingly (e.g., jquery-1.9.0.min.js) but this process will not be possible if you have already started using a newer version that doesn't allow backward compatibility with older versions because of API changes or some other reason, which means that you might open yourself up for troubleshooting problems when running the application in production mode on live servers.

How do You write HTML & CSS?

Although it seems like I've mentioned HTML & CSS along with JavaScript, these 2 technologies are quite different from each other when compared to writing code for client-side web applications developed using frameworks like AngularJs. Usually, HTML and CSS files reside inside the root directory and should never be placed under sub-directories because it is easier to maintain them this way.

1. If using HTML5 as a markup language then all your HTML tags should contain lowercase letters for their names so that they can be parsed properly by web browsers across different platforms. This also reduces portability issues as compared to writing tags with uppercase letters which might break an application if best practices are not followed during the development of separate pages/modules/components for a web application.

2. All your style sheets must start with an appropriate vendor prefix (e.g., "-WebKit-") denoting that they have been developed specifically for a corresponding browser. This will be automatically compiled into a single style sheet when source files are being processed by task runners Gulp or Grunt so that there are no issues with namespaces and specificity.

3. As far as CSS is concerned, it must be written by best practices under YUIDocs because specifying color values with leading zeros (e.g., #333333) makes them invalid whereas writing them without leading zeros can result in errors if hex code contains 3+ letters (e.g., #666666). Also, use valid keywords instead of color names whenever possible because they are not only easier to remember but also don't require you to write extra documentation for developers who are new to your development team. This applies equally to the HTML page as well where all the IDs must be prefixed with "UI-" because this naming convention has already been adopted by some of the popular HTML5 UI frameworks like Bootstrap, Foundation 5, and MaterializeCSS.

4. It's better to use single quotes instead of double quotes for text values within style sheets because they are not only more lightweight but also less error-prone when dealing with special characters, symbols, and numbers. Since there is no replacement for good coding practices across multiple applications developed using different technologies so it's essential to handle files in a way that they can be scaled up without any problems in the future.

How do you include JavaScript?

JavaScript is not included via simple <script> tags because that would create unexpected results and exceptions due to the brittle nature of HTML tags. Instead, it's better to follow a directory structure that indicates the file hierarchy within your application's source directory so that task runners like Gulp can execute all your JavaScript tasks in order without any difficulties.

Why do you need nodes for front-end projects?

Node.js is a platform built on Google Chrome's JavaScript runtime for easily building fast and scalable network applications using JavaScript. Although it was originally designed to compete with platforms like Ruby, Python, and PHP it can also be used as a task runner that automatically compiles LESS or SASS files into CSS stylesheets by following the coding standards mentioned above.

Why do you write cross-browser code?

It might seem like an odd question to ask at this point because of the dwindling market share of web browsers from companies like Microsoft and Apple after more than 10 years of intense competition against each other. However, they still account for almost 30% of all web traffic so it is for your code to work properly across multiple browsers without any problems.

What are the disadvantages of writing cross-browser code?

There are no disadvantages because it's being done by best practices to ensure that everything works as expected. However, there is a lot of manual testing involved so your web application might not work automatically on all browsers even though they are supposed to behave the same way. This is where QA teams play an integral role in ensuring that end-users do not run into bugs or issues during their daily usage of your product/service.

What is your workflow for coding HTML5 markup?

HTML5 uses lowercase letters for its tags which makes them more portable across different web browsers and applications developed using JavaScript frameworks like AngularJS, EmberJS, Bootstrap 4, and jQuery. However, it's also necessary to use many other techniques like progressive enhancement because single-page applications made using these frameworks are not guaranteed to work automatically on all web browsers without you having to make additional changes.

How are the sub-headings linked inside your article?

The sub-headings are specified within <h2> tags so that task runners like Gulp can link them to their respective sections by following the directory structure provided above. As far as content is concerned, it should always be written in a way that users do not have to click every time they want to go back or forward between different sections of an HTML page. This can be done by including distinct "anchor" IDs for every heading tag so that they can be linked directly to any specific part of your article using custom jQuery interactions.

How can I automatically format my code in VS Code?

VS Code provides users with a built-in tool that automatically formats their code according to the best practices mentioned above. You can use the keyboard shortcut Ctrl+K followed by Ctrl+F or you can click on Coding -> Format selection when using it in Visual Studio Code.

How do I run tasks using Gulp?

Gulp is an open-source build system used for automating front-end development tasks like compiling LESS/SASS stylesheets, minifying JavaScript files, and concatenating HTML5 markup so that it becomes more concise without any loss of functionality for the end-user. It uses NodeJS which means you have to install this dependency first before anything else because Gulp runs through Node's Common JS APIs directly.

Is it necessary to use Gulp in frontend development?

Not because every website works differently and has its own set of requirements. For example, you can also perform tasks using Grunt or even JSHint by simply following the examples provided above for NodeJS's native modules. In case you already have a preferred method of doing something then there is no need to change it just because someone else tells you that their way is better.

How do I install VS Code extensions?

VS Code provides users with a built-in extension manager which makes it easier for them to download third-party plugins without having to rely on Github repositories created by random developers who have found a workaround solution for their problems. Simply go to CMD+SHIFT+X and enter "ext install" followed by the name of a plugin you want to use.

Problem-solving skills over framework knowledge.

Framework knowledge is important because it helps you familiarize yourself with how to use them most effectively so that your website works properly. However, it's even more important to know why something is working or not working in the first place instead of just relying on blog posts created by random people who might want to market their products/services through any available means. This way, you can better judge whether they are really necessary for solving your problems or not.

Testing and Debugging

There are two different types of tests you need to perform when building a web application: unit and functional. Unit tests do not rely on any other part of the web application to run and they only use code stubs to simulate how your code behaves under certain conditions so that unnecessary dependencies don't affect your application directly. On the other hand, functional tests involve testing an actual user interface generated by your backend so that you can see if all CSS and JavaScript changes behave properly for users without reloading their browser windows.

In what cases should I avoid using frontend frameworks?

In case you only have a small website to develop then there is no point in downloading or understanding large pieces of software which might not even be necessary given the nature of your application. For example, if you are just working on a personal blog then there's no point in learning how to use Rails or Django when PHP will do everything that you want it to do. This way, you can better spend your time improving the quality of your code instead of viewing tutorials about things that seem so complicated only because they have different terminologies and notations compared to other types of programming languages.

How does Google PageSpeed Insights work?

Google PageSpeed Insights is one web application that provides users with feedback regarding how fast their website loads after being accessed by users who are located around the world. It also offers suggestions on how developers can make their websites load faster while at the same time protecting their security by making them aware of various attacks that their websites might be vulnerable to. This way, they can avoid being hacked or spammed with malicious code designed to disrupt the performance of a web application over time

Is it necessary for frontend developers to know how a browser works?

Yes, but only in case, you have no other choice because there are times when people want you to solve problems that seem very trivial from your point of view. After all, you don't understand what's going on behind the scenes. For example, if someone told me "The reason why this isn't working has got something to do with JavaScript" then my intuition is telling me that they're probably right given how much I know about my field and its interactions with other fields around it.

Tutorials and courses on web development are usually made for people who have no programming experience at all so that they can get a basic idea of what the workflow is like before they get serious about becoming professional front-end developers. However, not everything you learn through these resources will be enough to prepare you for what awaits you in the real world because there are many different types of problems that can limit your ability to think creatively when trying to solve them. This way, experienced frontend developers will eventually know how to push your buttons so that their code works perfectly while yours doesn't even once or twice despite following instructions precisely.

What do I need to know before learning any new framework?

You should always consider the type of company where you are going to work for because some of them want their employees to have a degree in computer science so that they can get hired. If you don't have one then try becoming familiar with popular languages like C ++, Java, and Python so that you will be able to write functional code on your own without needing to rely on frameworks that you might not understand.

Problems with 404 pages

The best thing about web applications is how easy it is for developers to make changes that are visible through the browser window. However, if there are too many errors happening during runtime then this means that something has gone wrong somewhere along the way which needs to be fixed immediately before users start complaining or attacking your servers with spam messages meant to damage your brand image.

What should I do if I'm having trouble focusing on my work?

This usually happens because of prolonged exposure to things that you find disturbing, whether it's the way your coworkers behave or how they allow their children to interfere with office activities. However, working at home and doing your best to avoid anything that disturbs your concentration is a good idea although you can also do this by drinking tea or coffee at regular intervals so that you won't get too sleepy.

How many problems should be solved in one day?

As long as developers are busy fixing bugs and adding new features before clients start complaining about broken links and server crashes then there is no such thing as having too much work to do on any given day. The reason why some companies have too much work to do is that they are already overwhelmed by the number of customers who are using their products. If people weren't satisfied with your app then they wouldn't download it in the first place so maybe you should be happy that it's popular enough for people to want more features added on top of everything else. Why not spend some time reading online tutorials about web development if you have the time?

What are good ways to learn programming languages?

The best way to learn something is through experience or by reading tutorials made by experienced developers who will teach you how to use new APIs and avoid problems that could end up disconnecting your site from search engines like Google which might result in users leaving before committing themselves to one platform over another.

Once you've built up enough experience then it's a good idea to talk to recruiters who are currently helping companies find talented front-end developers by sending them résumés that include a link to your GitHub profile. This way, everyone will know about the code that you have written in the past and how much more there is left for you to learn so that you can keep moving forward instead of staying in one place for too long without advancing or achieving anything else.

How does programming help productivity?

Programming is all about being creative so once you start thinking outside of the box when trying to solve problems related to server crashes and 404 errors, users might start feeling more confident in your abilities as a developer because they will no longer have to worry about their apps not working properly anymore.

What are good strategies for collaboration?

One of the most effective ways to work with other people is through pairing where two developers are assigned to work together on a single project until it's finished which will keep them from wasting time trying to fix problems caused by impatience or emotional outbursts. Once you've mastered how to build something without mistakes happening along the way then you can do this alone although it might take longer because there are fewer brain cells put into play when solving problems that have already been solved before.

Why is memory management important in complex programs?

If your app happens to become popular then you might run into memory management issues because too many users will start using it at once which will result in the whole system crashing to protect itself from overheating. This is why memory management is important if you want your program to run smoothly without crashes or bugs taking place every few minutes because the user might end up associating your app with these symptoms instead of getting rid of them altogether.

What are good ways to increase productivity?

The best way to do this is by cutting back on meetings and superfluous tasks that many managers tend to assign their employees so that they can save time for themselves. The next step would be writing down everything that needs doing before finding out whether it's possible to do them all at once instead of working on just one thing until it's finished after which you can move on to work on the next task. Some developers might not have time to write documentation but there are some things that you need to do so that the entire team can be on the same page during brainstorming sessions which will help when it comes to assembling a working program without having to go through too many bugs and other issues along the way.

Front-end developers. End development skills check

Front-end developers are not just web designers because they have to know how to code their designs before uploading them to the server so that they can help other people share what they have come up with without having to spend much time using different kinds of software for it to work properly when being uploaded onto social media websites or through emailing it around to get people excited about working on their app together. This is why front-end development is all about solving different kinds of problems instead of just lazing around without doing anything productive which means that you might have a hard time getting hired if your résumé doesn't include any examples of projects where deadlines were met without too many issues taking place along the way.

How to choose a Code Editor?

Choosing a code editor is all about finding something where the shortcuts are easy to remember so that you don't have to keep referring back to the user manual every time you make a change. It's also important for it to come with syntax coloring which will tell you what data type each section of your program is using when solving different kinds of problems without knowing whether they're writing in C++, Java, or some other programming language entirely because this can vary from person to person based on how complex their work happens to be.

Git and Version Control Systems

It's important to work on your code using a version control system because this will allow you to see how the program changes over time so that you can go back in time whenever it feels like something is about to break. If you used one of these systems then it should be fairly easy for you to roll back to an earlier state before something went wrong because you're given access whenever other people need help debugging their work which means that they're not just stuck trying to get through problems by themselves even though there might be dozens of users all trying out your app at once without having to worry about its performance getting bogged down by too many crashes or bugs popping up every few minutes.

What are some good ways to improve my skills?

The best way to improve your skills is by reading books or programming language references whenever you need some help with solving more complex problems because it's important for you to know what you're doing before trying out new things. There are plenty of tutorials around on the internet but they might not be written in a way that will suit everyone's learning style which means that you'll have to figure out whether this is something that works for your needs or not based on how well thought out it happens to be.

Programming languages and frameworks

Everyone has their preferences when it comes to programming languages so there isn't any consensus as far as selecting which one is best for making applications so most people just go with whatever they feel most comfortable with instead of trying out new things. Even though this might change over time, most people still think that the programming language they were working with at their previous job is still one of the best ones to use so there isn't too much diversity when it comes to which languages are preferred by people who already have experience with building applications before.

Frameworks

Front-end developers usually come up with their frameworks and libraries for others to use whenever they decide to do something on their own instead of just using a pre-existing program or library because these frameworks help them get started without having to spend too much time writing code from scratch every single time. Different frameworks work better depending on what kind of project you're hoping to build so your decision will mostly be based on how quickly can you get started and how much time you're willing to spend learning how to use it.

What kinds of projects do front-end developers work on?

Front-end developers usually work on apps that can be used by either a single person or group of people without too many problems taking place during the process so they handle most kinds of programming projects except for those related to back-end development which is usually handled by back-end developers with limited front-end experience. Front-end developers might work on smaller apps with only a few dozen lines of code but most end up working on larger ones with thousands or millions of users that need their feedback in order to avoid any issues with performance or crashing that could them losing all the data they've put into it.

How is front-end development related to other parts of my business?

Front-end developers are usually somewhat related to all parts of your business because they need support from everyone else whenever any obstacles might interfere with their work. Front-end developers might have trouble working with back-end programmers who don't understand what kind of problems front-enders face regularly but they'll also need the help of project managers to make deadlines and stay organized with their time management skills even though they might not sit close together during meetings or share an office space.

Front end frameworks

For front-end developers, it's important to have a good understanding of what kind of programming languages are being used by other members of your team because you might need to solve some problems that come up with the rest of the coding language you're working with so it's important for front-enders to know about HTML, CSS, Javascript or any other back-end languages they might be using on their system.

React is one of the most popular frameworks out there and its best feature is how quickly front-end developers can go from writing code to seeing their changes appear in real-time which makes debugging and testing easier. It uses JSX files as an extension on top of React that allows them to write markup HTML inside the JavaScript html files to combine them into one single file that's easier for front-enders to write in instead of splitting up their code based on where different parts are being displayed.

React can also be used with Flux which is a kind of application structure built by Facebook designed to help developers avoid rewriting the same lines of code over and over again. React uses functional components as its basic building blocks so they're easy to use even if you don't have any Javascript knowledge but some advanced structures can be hard to manage without knowing how things work under the hood. React is only compatible with modern web browsers so older versions might not have enough support from everyone using it right now which can cause problems during development.

Emberjs is a more traditional framework that works with front-end developers who have previous experience with Javascript or other traditional web frameworks. It has a strong dependency on the Handlebars templating engine so it's easier to create views, components, and helpers using HTML instead of worrying about language compatibility issues all the time.

Emberjs is designed for professional-grade front-end development so it can be used in larger projects that have more complicated needs without any problems appearing during development even though it uses Ember Data as its data model library which is still being developed by core members of the Emberjs team instead of having an automated service like some other popular frameworks out there.

AngularJS was developed by Google to help them write better code both on the client-side and back but today most versions of Angular that are being used are just the second version of the framework known as Angular 2 which is a complete rewrite with no backward compatibility. It can be used by front-end developers to create single-page applications and it has a dependency on TypeScript for writing functions and variables instead of Javascript so it's easier for developers who have previous experience working in other languages to learn how things work under the hood without having any issues happening during development or runtime.

Ember vs React: What should you choose?

When it comes to choosing between Ember and React, you want to check if your team already uses Javascript because React requires developers to know at least some language features before they start using it while Ember doesn't require any knowledge but it's not for beginners either. Ember includes Handlebars, HTMLBars, and Fastboot which are components that can help you develop faster but if those features aren't included in your project then it might make sense to switch to something else instead.

Ember is good for creating large-scale applications without any problems coming up during development as React does because it has a strong set of features as well as the ability to use older versions of Javascript back to ECMAScript 1.8 while React only works with modern web browsers so there's no need to worry about compatibility issues popping up at the last minute during development like some other frameworks out there.

React isn't compatible with older versions of Javascript and Angular doesn't work with any of them either which can be a problem when dealing with compatibility problems in the future. Ember has better documentation than Angular and React because it has guides for beginners, reference pages to let you check how things work under the hood, and a collection of tutorials about common problems. Angular only has a developer guide that covers some basic topics while React doesn't have anything like this even though it's still being developed by the Javascript team at Facebook.

Ember offers more chances for further learning including its front-end toolkit called Ember CLI that can help developers develop their apps faster while also developing their skills without having to learn new things from scratch. It provides a router for creating single-page applications and an adapter for using databases on the web as well as an ember-CLI addon for creating user interfaces.

React doesn't include anything like Ember CLI and it has no official router library that you can use during application development, however, there are many custom options available that can be used instead to create single-page apps or other variations including GraphQL and Flux architecture. The best part about these frameworks is the fact that they both offer a large collection of components and features so you can pick and choose what works best for your projects without having to build every component from scratch because different companies have different needs.

Ember uses Handlebars as its main templating engine but it allows developers to use their libraries if necessary which means you aren't locked into the default dependency if it doesn't work for you. React can be used with JSX or ES2015+ but it has an official plugin that allows developers to integrate it with other templating libraries including PureRenderMixin, HyperScript, JSX, etc.

HTML & CSS

Both React and Ember have components that can be used to create user interfaces, however, Ember has Ember CLI that was designed specifically for front-end development while React allows developers to use whatever tools they want including their template engines instead of JSX or other variations.

Ember includes HTMLBars as its templating engine but you can also integrate Handlebars into your project if needed. React comes with JSX but it doesn't require developers to use it because they could always write everything by themselves without having any issues during runtime or development.

HTMLBars is faster than Handlebars when rendering data because it's easy to make optimizations using the latest ECMAScript/TypeScript features where you can check how things work under the hood. React uses a virtual DOM that updates elements in place instead of reflowing the page which means it's easier to write new features using JSX according to developers.

Ember includes SASS for writing CSS while React doesn't have anything like this because its library comes with an inline styling solution that only works on HTML tags, however, developers can include CSS libraries such as Bootstrap or Foundation to solve this problem quickly during development. Ember is built-in and well-supported by the Ember team so there won't be any compatibility issues when working with different applications in the future such as updating them if necessary.

React creates components dynamically instead of creating all of them at once which ensures better performance during runtime and also improves memory usage when rendering lists. It also updates components in place which makes it possible to update only the parts of the DOM that have been changed because React can compare virtual elements with a real dom and see what needs to be updated instead of updating all elements on the page, but this means that components should be written as functional ones without having any state or other unnecessary features.

Conclusion: Ember is better for larger projects because it has a unified front-end toolkit called Ember CLI while React doesn't offer anything like this even though developers can use their tools during development such as webpack or grunt. One major benefit about using React is the fact that it's fast and easy to debug, however, you won't be able to write everything from scratch if your project is large. Ember has features like HTMLBars and SASS that make it possible to move faster during development while React has an out-of-the-box solution with JSX which is easier to use, however, its debugging tools aren't as easy to use as the ones found in Ember.
