Requirements for front-end development
Front end web development requires the following technical expertise:
1. Good grasp of HTML5 & CSS3 technologies.
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.

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.
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.
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.
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.
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?
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?
How do You write HTML & CSS?
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.
Why do you need nodes for front-end projects?
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?
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?
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
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?
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.
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
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.
Ember vs React: What should you choose?
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.
