Top-5-Free-Open-Source-JavaScript-Frameworks-For-Web-Developers-in-2020

JavaScript is one of the most widely used, flexible, dynamically typed languages and its popularity is rising day by day. Over the years, many excellent JavaScript frameworks have released, and new ones are coming day by day hence there are always many choices for you.  So, which framework should you learn? It’s always tough to choose the best one for development. Now if you’re confused about which one is the right choice for you, don’t worry because here are the top 5 JavaScript Frameworks that will make your development easier and smoother.

1. React

React is the leader in the JavaScript world, created and maintained by Facebook, is the most influential JavaScript-based Web framework. React has earned massive popularity within a short span and over 2 million websites like Facebook, Instagram, Yahoo, Netflix, Dropbox, etc are using React for building interactive and complex UI. It uses a reactive approach for front-end web development and takes care of the dynamic User Interface of the web pages with high incoming traffic. It is Component-based and component logic is written in JavaScript instead of templates to pass rich data through your app. React can be your first choice for creating an awesome front end for the following features:

  • Declarative views help to debug faster. Create interactive UI Design simple views for each state in your application and efficiently update and render just the right components using React.
  • Component-Based approach helps to manage each encapsulated component’s state, to design complex UIs.The whole web page divided into a small self-contained module known as a component.
  • React JSX, a markup language makes writing React components which is a fusion of HTML into JavaScript.
  • Unidirectional data flow only supports downstream or upstream data flow which makes the logic more predictable and easier to understand.
  • Virtual DOM is a representation of a DOM object which creates a virtual copy of the original DOM. In React every DOM object has a corresponding virtual DOM for one-way data binding to quickly manipulate the virtual DOM rather than updating the original DOM.
  • LOWA or Learn Once, Write Anywhere helps you to develop new features in React without rewriting existing code.
  • React Native, a custom renderer for React uses native components instead of web components. React along with native platform capabilities used to develop applications for Android, iOS.

2.  Angular

 A JavaScript-based open-source front-end web framework Angular is one of the most powerful, efficient, open-source framework which is the part of MEAN stack. It is also the main rival of React, developed, and maintained by Google. AngularJs is very useful for developing a Single Page Application (SPA). This development framework is very popular for helping developers to combine JavaScript with HTML and CSS. It loved by millions for its productivity and scalable and over one million websites like google.com, youtube.com, etc. are using Angular for its awesome tools, speed, and performance.



  • MVC architecture or Model-View-Controller architecture is one of the most essential features of AngularJS, which is divided into three elements, i.e., the Model, View, and Controller to simplify both the development and the testing of single-page applications.
  • SPEED & PERFORMANCE of Angular is uncomparable. Angular helps to develop progressive modern web apps with high performance, offline mode, and zero-step installation.
  • Two-way binding is a very useful feature of Angular which helps to build a link between Model and View, in which the View reflects changes made in the Model and vice-versa.
  • Incredible Tools of Angular are very useful to increase your productivity focus on building amazing apps.  Command-line tools help to build, test, then instantly deploy. use simple and powerful template syntax to create UI views and  Get intelligent code completion, instant errors, and other feedback in almost every IDEs.
  • HTML UI leads to a more organized and simplistic UI. HTML, a common and declarative language with elementary tags that are very easy to understand than the complicated Javascript code. So, If you’re looking for a quick, simple, and easy solution, then this is it.

3. Vue.js

It is an open-source Progressive JavaScript Framework for building creative UI and high-end single-page Web applications.  Vue is designed to be incrementally adoptable which gives easy integration into projects that use other JavaScript libraries. Vue supports declarative rendering using template syntax to provide data to the DOM and it is an excellent framework for beginners. Vue has quickly risen to prominence in the Web development community and giving an extreme challenge to both Angular and React. Big companies like Grammarly, Adobe, GitLab, StackOverflow, PlayStation, etc. are relying on Vue for their websites UI and almost over 671,000 websites that using  Vue. js in 2020.

  • Versatile: provides an adoptable ecosystem to scale between a library and a framework.
  • Progressive:  it gives you the power to plug into any web app that is running on any other framework, without making any changes.
  • Beginner-friendly:  Vue is the best framework to start building web applications if you already know some HTML, CSS, and JavaScript.
  • Reactive:  it is a fast and responsive framework which takes the user input, regardless of network speed or latency,
  • Small in size: Does size matter? -Of course, One of the greatest advantages of Vue.js is its size which is surprizingly18–21KB.
  • Complexity: It is super simple to use with quality documentation support. You can build simple applications very easily using Vue.

4. Meteor
