The collection of JS code libraries that provides pre-written JavaScript code that can be used for conventional programming functions and tasks is known as JavaScript Frameworks. It enables you to build websites or web applications efficiently. Below mentioned are the top JavaScript Frameworks which you need to look after in 2021.

Top Javascript Frameworks to look after in 2021


Developed and maintained by social media giant Facebook, React is an open-source, component-based, declarative javascript library for large data-driven web application interfaces. Developed in 2013, React presents its own concepts to stand away from other frontend web frameworks. It incited the development of plenty of supplementary tools to reach immense flexibility and scalability. The React javascript framework leads the search volume at 57.5%.

Features of React.js:

  • It helps in creating dynamic and interactive UI for both websites and mobile applications.
  • React.js uses the declarative approach which makes the code easy to debug and readable.
  • React.js uses the theory of “Virtual-DOM object”. A representation of real DOM elements produced by React components before any changes are made to the page is Virtual-DOM.
  • It uses JSX, which is a specialised markup language that mixes HTML into JS.
  • React uses “FLUX” for unidirectional flow of data or say one-way data binding.
  • React.js is component-based, which means everything is a component of the web page divided into little components to create a view. Components are used to describe the interactions and visuals in applications.


In 2016, Google developed one of the most powerful and effective open-source JavaScript frameworks called Angular. It uses the MVC (Model-View-Controller) design pattern where Angular changes from MVC to Component-based architecture in version Angular 2.X. The framework uses the language CoffeeScript and TypeScript, which are supersets of JS.

Features of Angular

  • Angular framework is a cross-platform web framework for growing Web Apps, that is, they are reliable, capable, and installable. These pillars modify them to feel like a platform-specific application.
  • Using the same Angular method to access native OS APIs, desktop installable applications can be created across Windows, Mac, and Linux.
  • Angular framework is the Universal platform that serves both for the frontend and backend by using some code and library which is referred to as Angular Universal.
  • Angular framework has the component referred to as Router, using Router angular apps load swiftly.
  • Angular framework creates UI views with the help of simple template syntax.
  • A special Chrome extension, Angular Augury, is used in order to debug applications.

Commonly known as Vue, Vue.js is an open-source JavaScript framework which is used to develop enriching user interfaces. As Vue is a progressive framework, it can be easily integrated with the existing projects and with other JS libraries. Being a reliable platform for developing cross-platform applications, one of the most winning features of Vue.js is its dual integration mode for creating high-end single-page applications.

Features of Vue.js

  • Like in React.js, Vue.js uses the concept of Virtual-DOM. The framework is the clone of the primary DOM elements which absorbs the changes made in the DOM present in the form of JavaScript and correlates with the primary data.
  • Vue.js is extremely simpler and less limiting than Angular and also worth thinking instead of React.
  • The framework uses the Vuex library, which is a Flux-like state management tool.
  • A feature to mix HTML layouts with JS is known as Data-binding. One has to use v-if or v-bind to interpolate values to templates from the component logic.
  • A JS library known as Weex supports Vue syntax and is used for mobile development.


An open-source Javascript Framework, Ember.js is used for the creation of a wide range of web applications. Ember javascript is an amazingly flexible and adaptable framework. The creation of the development stack can be done by Ember or other tools. Ember offers programmers several layouts and components and its own backend architecture to provide programmers with all tools for developing their own app-specific HTML tags.

Features of Ember.js

  • Ember javascript is an open-source framework.
  • It is used for developing javascript apps that can be maintained and reused.
  • The framework utilizes CSS and HTML as the core of its development model.
  • For debugging of the Ember applications, Ember Inspector tool can be used.
  • Ember uses templates that help to automatically refresh everything once the content is modified.


Meteor.js is one of the most widely used backend javascript frameworks. The basic concept of Meteor is developing a backend in less time. This is the reason why frontend developers can run backend properly with Meteor without flipping between programming languages like Python, PHP, etc. It lets you use one language everywhere.

Features of Meteor.js

  • Meteor.js uses the same code for desktop, web and mobile apps.
  • The framework has open-source IDevE and enables you to let you design real-time web applications.
  • Meteor.js provides full-stack features for developing web apps.
  • It offers necessary packages for famous frameworks like Bootstrap, Backbone.js, etc.
  • The framework has built-in live-browser reloading.

All the JavaScript libraries and frameworks that have been explained above contain the great potential to grow exceptionally in the future. Every framework has its own advantages and disadvantages, and the programmer has to figure out which one has the features he/she needs for their project.
