Top Front-End Frameworks in 2021

A front-end framework is mainly a group of tools & libraries that allows facilitating and speeding up the development process of a project. While using a vanilla code, you might have come across various issues of lack of modularity, highly-complex-code, and have to spend enough time to develop basic functionality.

All these issues can be resolved with the help of Front-end frameworks. They emphasize more on component-driven development and make it easy for you to maintain the code, enhance code organization, allow code reusability, and implement good design patterns.

As per one survey of stack overflow of the year 2019, the majority of developers who are not working on any technology but prefer developing web apps using react.js, vue.js, and angular.js.

Before starting any project, you should be familiar with different kinds of frameworks available for web and mobile app development.

Because, the framework you choose will have a great impact on the overall development of the project. Hence, you should have clear understanding about the front-end/backend frameworks as well as cross-platform app frameworks.

To simplify your task, in this blog, we will provide the list of most popular front-end frameworks that you can use to develop excellent web & mobile applications.

Front-End Frameworks: Comparing the top frameworks in the Market

1. React.js

React is one of the most popular frameworks since its inception. React is an open-source and component-based JavaScript library with the JSX syntax.


Jordan Walke, one of the Facebook software engineers, built a prototype of the React while facing issues in the work of the Facebook app that happened during the update of the network.

He used XHP and JavaScript combination to build a library in 2011. Facebook later released the open-source JavaScript tool with the name React.js in 2013.

The main feature of react.js is virtual DOM; however, it only offers one-way data binding. React.js provides great performance; it is SEO-friendly and allows you to write JavaScript code with ease.

Where can it be used?

React is a declarative, efficient, and adaptable JavaScript library that is used to develop user-interfaces for single page web apps and mobile apps.

As it is a library, it is essential to consider some other libraries to build highly complex applications, here we suggest Redux and React Router.

If you are not familiar with react.js, you can also hire react.js developers from professional development companies, they will provide the best single page apps.


  • React works well with isolated components; hence you can utilize the components anytime you want.
  • Virtual DOM ensures quick rendering.
  • One-direction data flow provides stable code.
  • A vast community of developers across the globe.


  • Requires more libraries to develop complex apps.

Angular is a component-based framework and offers two-way data-binding. Angular utilizes a hierarchical dependency injection system with the help of declarations, constructor functions, and providers.

Angular utilizes flux architecture, where change detection is possible via unidirectional data flow, thus enhancing the speed of developing apps.

Where can it be used?

Angular is useful for the web as well as mobile app development. Apart from developing a single-page app, angular can also be helpful to create a multi-page app. It allows you to render applications on both browsers as well as mobile devices. Angular consists of inherent extensions of the server-side rendering of apps.


  • Due to its lazy loading feature, applications run faster.
  • Independent components are quicker to replace, handle, and scale-up.
  • Due to independent and self-sufficient components, it is reusable and test-friendly.
  • Angular requires TypeScript, which ensures expressive code, improved navigation, and better-quality product.
  • Useful to create single-page and multi-page apps.
  • Apps built using Angular performs in 5x better way as compared to AngularJS.


  • Must-learn TypeScript.
  • Angular 2 is a fully new version of AngularJS, hence old methods used in AngularJS required to be fully migrated; that’s something that the majority of developers don’t like.
  • Difficult to manage components.
