Top 20 Front-End Developer Skills You Need to Know

Our lives as developers appear to be highly competitive in a world where the employment of several programming languages is commonplace. In today's programming world, web languages are demanding but progressive options for comprehensive learning and career advancement.

In this post, you will learn about the best Front End Developer talents that will help you advance your career in web development. Along with that, we have offered the best technical and non-technical Front End Developer abilities for job advancement.

Who is a Front-end Developer?

The first and primary question that comes to mind is, "Can I be a front-end developer?" Before I answer this question, let me define a front-end developer. Front-end web development is the creation of a website's GUI (graphical user interface) to make it more presentable and engaging. HTML, HTML5, CSS, CSS3, JavaScript, JQuery, TypeScript, Angular, and React are some of the computer languages that allow GUIs in web development. Thus, a language-skilled developer is also a front-end developer. To become a front-end developer, you must complete various professional courses. Knowledgehut offers the top front-end developer courses.  

Technical Front-End Developer Skills 

  1. Beginner's Technical Skills:

Amateur web developers must be familiar with basic programming languages such as HTML, CSS, and JavaScript. A brief description of these languages is provided below. 

  • HTML: HTML or HyperText Markup Language is the basic building block of any web page. This is the only language well understood by web browsers. All web pages in the world consist of HTML. 

  • HTML5: HTML5 is the latest version of HTML. It contains a lot of extra tags like

    ,,,,, etc There are some shortcut tags as well, like tag.  


  • CSS: CSS or Cascading Style Sheet is the styling part of the web page. It beautifies the website by providing many formats, positioning, font styles, and colour. The Box style with borders is becoming a trend nowadays.    

    • CSS3: CSS is just the basic version of styling. At the same time, CSS3 is the advanced version of CSS with a responsive design. It also provides splitting up styles into modules. To learn CSS, See Section: "Who is a front-end developer?"


JavaScript is the programming language of any web page recognized by web browsers. It is a scripting language with a 'Document Object Model' and an object-oriented language with a prototype model. It has variables, constants, control statements, loops, functions, arrays, objects, and numerous more features that improve the functionality of a web page. JSON, or JavaScript Object Notation, is quickly becoming the preferred data communication method. Some institutions also offer front-end web development courses, such as KnowledgeHut's finest front-end developer program. It encompasses all aspects of front-end development in a single course.    

   3. Intermediate Technical Skills:

Website designers who have basic skills can advance to the next level, where they can learn about JQuery, TypeScript, AJAX, and JSON. Let us discuss these languages briefly: 

  • JQuery: JQuery is a library of JavaScript. Jquery is designed to make HTML DOM tree traversal and manipulation easy. It is very useful for event handling, AJAX, and CSS styles. However, it is mostly used for its ease of functionality and CSS Animation. JQuery is free, open-source software. According to Wikipedia, as of May 2019, jQuery is used by 73% of the 10 million most popular websites. JQuery library is available in the downloaded format and CDN through Google, Microsoft, jquery.com, and many others. JQuery can be downloaded from https://jquery.com/download/.  

  • Typescript: Typescript is a strongly typed, strict, object-oriented programming language that builds on JavaScript. It is developed and maintained by Microsoft. Typescript is the base of many advanced web languages like Angular, Vue.js, and React.js. The Typescript course includes the React.js course and is under full-stack front-end web development. 

  • AJAX: AJAX is Asynchronous JavaScript And XML. It is not a programming or scripting language in itself; rather, it is a technology by which we can perform asynchronous request-response cycles. According to Wikipedia, "Ajax is a set of web development techniques that uses various web technologies on the client-side to create asynchronous web applications". With the help of this technology, web applications can send requests to and receive responses from a server asynchronously without disturbing the current page's behaviour with this technology's help. In current-day websites, no one can imagine a page without AJAX. AJAX comes best with JavaScript and JQuery. To learn AJAX in JavaScript or JQuery, See Section: "Who is a front-end developer?" 

  • JSON: JSON has the full form JavaScript Object notation. It is a lightweight data interchange format. This technology uses JavaScript prototype objects to simply the most complex task of web technology – data transfer. JSON is an object-wise syntax for the serialization of objects. It can contain data types like arrays, numbers, strings, Boolean, and even null. To work with JSON files, we get a lot of encoder and decoder libraries for various server-based web languages like JSP, ASP.Net, MVC, Python, etc. JSON comes best with JavaScript and JQuery.

4.Responsive Technical Skills:

Tablets and smartphones are extremely popular nowadays. Responsive websites can be seen on various devices, including PCs, laptops, notebooks, tablets, and smartphones. A responsive website adapts to the size of the display screen, providing forms for menus, tables, photos, animation, and other elements. To make a website responsive, we must have various skills, including Bootstrap, Foundation, HTML5 Boilerplate, and UIKit. Let us explore these skills briefly: 

  • Bootstrap: Bootstrap is a distributed library of CSS and JavaScript files. With Bootstrap, we can easily and quickly design and customize responsive mobile-first websites. It is an open-source toolkit featuring SASS and MIXINS. Many websites rated Bootstrap the world's most popular responsive website designer toolkit. It contains a responsive grid system, extensive prebuilt components, and powerful JavaScript plugins that enhance any site's responsiveness. It can be obtained from its official site: https://getbootstrap.com/docs/5.0/getting-started/download/. The bootstrap course comes under full-stack front-end web development.  

  • Foundation: According to the Foundation's official site, it is "The most advanced responsive front-end framework in the world. A Framework for any device, medium, and accessibility. The foundation is a family of responsive front-end frameworks that make it easy to design beautiful responsive websites, apps, and emails that look amazing on any device. Foundation is semantic, readable, flexible, and completely customizable". It offers a do-it-yourself approach. We can create unique and customized websites by using this library. Many developers find the Foundation to be more complex than Bootstrap. According to them, Bootstrap helps us easily create simple yet elegant websites and needs very little knowledge of CSS and JavaScript, while Foundation requires more basic skills than Bootstrap. The foundation library can be downloaded from https://get.foundation/. 

  • HTML5 Boilerplate: This Library is very popular for its cross-browser compatibility. According to Wikipedia, "Boilerplate code or just boilerplate are sections of code that are repeated in multiple places with little to no variation". A boilerplate is a template rather than a library. An HTML5 boilerplate is added at the start of any web project and subsequently added to all its HTML pages. HTML5 Boilerplate can be downloaded from https://html5boilerplate.com/. 

  • UIKIT: A UIKIT is a library or tool that helps web developers develop module-based websites. It has a modular-based approach to website design. We use UIKIT in two ways. For Rapid Prototyping, we use UI KIT to mock up web pages. We need UI KIT to create customised kits for the final product design according to our project needs. UI KIT can be downloaded from https://getuikit.com/. 

5.Advanced Technical Skills

As we go toward complete proficiency in front-end website creation, we typically begin working with modular programming. We categorize our website into components, services, libraries, and modules. Some of the advanced technical skills necessary to grasp this strategy are Angular, React.js, Vue.js, and Node.js. Let me briefly discuss each of these technologies:

  • Angular: Angular is a free and open-source framework that is built for developing web applications. Angular is a rewrite from the team that built AngularJS. It is a typescript-based framework constructed by the Angular Team at Google and supported by a community of individuals and corporations who constantly groom the framework. Angular CLI can be downloaded and installed from node.js by the command "npm install -g @angular/cli". 
  • React.js: React.js is a free and open-source framework for developing web applications. Based on UI components, it is a front-end JavaScript library built for designing user interfaces. Meta and a community of individual developers and companies maintain React. React and Angular are mostly used in SPA (Single page applications). React.js can be downloaded and installed from node.js by the command "npm install -g create -react -app" and then "create -react -app –v". 
  • Vue.js: Vue.js is a front-end JavaScript framework. It was created by Evan You and is maintained by Evan and its core team members. The Vue.js library is used for building user interfaces and SPAs (Single Page Applications). Vue.js can be downloaded from https://v2.vuejs.org/v2/guide/installation.html. 
  • Node.js: Node.js is an open-source runtime environment. Node.js is a cross-platform, back-end JavaScript environment that executes JavaScript code without a web browser. It runs on the V8 engine. Node.js can be downloaded from https://nodejs.org/en/download/. 

Non-Technical Front End Developer Skills

As we have previously reviewed technical skills in our last article, let us go over some of the non-technical skills briefly:  

  • Web Security:

Hacking into web servers is the most common security threat for online businesses. Web security is the protective measures taken against web-related cybercriminals and threats to web communication. Web Security deals with the stack of protocols in HTTPS. It is a must for any transaction-related online activity. Some sectors using Web Security skills are Banking, Insurance, Law and Order, E-commerce, personal mail accounts, personal profile maintenance accounts, etc.

  • SPA:

Single Page Applications is the method in which only one page is dynamically loaded and re-loaded for every request made to the website. It is a preferred skill for web applications. Angular, React, etc., are all specifically designed for SPA. 

  • UI/UX:

UI stands for user interface, and UX stands for user experience. UI/UX skills make the end web projects very user-friendly. Here, we understand the marketed audience and design our web apps according to the needs and ease of the client.

  • Progressive Web Apps:

According to Wikipedia: "A progressive web application (PWA), commonly known as a progressive web app, is a type of application software delivered through the web, built using common web technologies including HTML, CSS, JavaScript, and Web Assembly". Progressive Web Apps can be called from any browser on almost all responsive devices. Learn how to make API calls correctly in Angular and create progressive web applications.
