As per the Stack Overflow Survey, JavaScript is the most renowned and driving language among web developers and overwhelms the market with 62.5% offers in the programming language domain.

jQuery is a JavaScript library: an assortment of modules and extensions that makes working with JavaScript quicker and simpler. As opposed to coding everything from the start, jQuery lets you add pre-built components to ventures, and personalize them later on if required. You can utilize jQuery for things like timers, search autocompletes, and even consequently revamping and resizing matrix formats.

3. ES6

ES6 alludes to adaptation 6 of the ECMA Script programming language. ECMA Script is the institutionalized name for JavaScript, and adaptation 6 is the following adaptation of 5, which was rolled out in 2011. It is a significant upgrade to the JavaScript language and adds a lot more features with the objective to make enterprise-scale development simpler. 

ES6 or EcmaScript 2015 is a noteworthy update to JavaScript with numerous valuable highlights:

  • Template Strings
  • Spread Operator
  • Rest Parameter
  • Modules 
  • Generators
  • Destructuring
  • Classes
  • Arrow Functions

4. Basic knowledge of Server Side Rendering/Scripting

Server-side rendering is the procedure of both structuring and serving an application from the server when a client demands a page. This resulting application is frequently an HTML page that can rapidly be parsed by the client's program so as to render the application. The server "rendering" is setting up that view for the client to render, not really rendering the page on a browser being executed on the server. This kind of rendering has been well known in the course of the most recent as a simple method to populate pages with information in one excursion to the server. Having a basic understanding of how the server-side works enable the front-end developer to create a better architecture in terms of the quality of the code and also be familiar with the authentication procedure in an app.

5. You can’t ignore the Web Performance.

You can build the greatest site ever yet on the off chance that it performs slowly on the client's end, it would be totally futile. Web performance is the measure of time it takes for your webpage to load. In case you're having issues with execution times, there are steps you can take to improve them, for example, streamlining pictures (scaling and compacting pictures for maximum web performance) and minifying CSS and JavaScript.

Ensuring high-quality web performance may take a part of your precious development time, but that can be taken care of by automation tools like Grunt and Gulp. In the continuous journey for increased utility and performance, it'll be to your greatest advantage to get acquainted with them.

Web performance tells about the time a website takes to load. If you’re having trouble with performance time, there are various steps that you can choose to improvise them, such as optimizing images and minimizing CSS and JavaScript.

6. Making coding easier with CSS and JAVASCRIPT frameworks.

CSS and JavaScript frameworks are assortments of CSS or JS records that perform various assignments by giving unified utility. Rather than beginning with a blank page, you start with a code document that has plenty of JavaScript present in it.

The advantages of frameworks originate from the speed with which they enable you to create extraordinary looking, responsive web UIs - particularly in the event that you are new to the client-side development. For example, Bootstrap - which is the most renowned CSS framework - enables you to take a plain HTML web application and change it into a nice looking website with a couple of class names. If you invest a little more time, these frameworks will enable you to make an exquisite, responsive UI without knowing advanced programming languages.

Some of the most popular frameworks:

  • Semantic UI
  • Skeleton
  • Tailwind CSS
  • Spectre


  • Angular
  • React
  • Vue.JS
  • Meteor
  • Node.JS
  • Backbone.JS
  • Aurelia

7. Chrome DevTools

The cutting edge internet browsers come furnished with developer tools for testing. These tools enable you to test the pages in the browser itself and discover how the page is deciphering the code. These tools comprise of a code inspector and a JavaScript console that enables you to perceive what the runtime HTML on your page would look to the end-user, what CSS is related to every component on the page, and furthermore enables you to alter your HTML and CSS and see the progressions live as they occur. The JavaScript console enables you to see any mistakes that happen as the browser attempts to execute your JS code. Other than that, it also includes Performance, Memory, Application, Security, Network, Customize and Control DevTools, and more

9. Git Version Control

Git is a variant control framework utilized for the following changes made in codes during the development process. It empowers the front-end developers to work together on ventures, which enables them to finish the project quicker. As a front-end developer in the contemporary world, the significance of git can't be emphasized enough. Pretty much every job description for a developer makes the fundamental knowledge on git a necessity. Git makes it easier to go back to the previous version of your project in case you mess up in the recent one. To utilize git you should be acquainted with the CLI.

An adaptive design, on the contrary, utilizes numerous fixed formats that don't resize, and the site will pick the most ideal format for the screen size.

11. Test-driven Development to make it to the top.

TDD signifies "Test Driven Development". The essential objective of TDD is to make the code more clear, basic and remove the bug. Test-Driven Development (TDD) is a programming practice that guides designers to compose new code just if a computerized test has fizzled. This keeps the code away from duplication and redundancy. Test-Driven Development begins with structuring and creating tests for each little utility of an application. In the TDD approach, first, the test is created which determines and approves what the code will do. In the typical Software Testing process, we initially create the code and afterwards do the testing. Tests may fall flat since tests are developed even before the development procedure begins. So as to breeze through the assessment, the development team needs to create and refactors the code. Refactoring a code implies changing some code without influencing its conduct.

12. CLI to add feathers to your cap.

From multiple points of view, the extension of GUIs (Graphic User Interfaces) into processing was one of the most exceptional things to ever occur. GUIs can be luring with regards to web development just as coding, and they're frequently advantageous as well, however, a universally handy GUI unquestionably has its impediments for some particular applications.

You should be able to easily express your designs and give out suggestions. You should realize how to request help on an undertaking you discover hard to finish from a partner or senior developer. The skill of communication may look easy, however, it's perhaps the hardest aptitude to ace. 


Software engineers, well acquainted with agile development, are very high in demand. The market’s requirement is enormous and most likely, the gap is not expected to be filled any sooner due to the increasing need for skilled developers, thereby opening the doors for a vast scope for the budding developers.
