AngularJs vs. ReactJs: Which is the Best Choice in 2021?

JavaScript is a text-based programming language that allows you to develop interactive web pages on both the client-side and server-side. Angular is an open-source JavaScript framework that is written in TypeScript, React is an open-source JavaScript library that was developed by Facebook.

Let’s look at the differences and similarities and find out which one is best in 2021!

What is AngularJS?

AngularJS is an open-source web framework based on JavaScript that is used in easily building web applications. It is developed by Google. Its primary purpose is to develop single-page applications. Its simple architecture makes it easy for developers to create mobile and web applications rapidly. Its Model View Controller (MVC) structure also allows for two-way data binding, which speeds up development and achieves an interface with less code in the project.

Advantages of AngularJS:

  • Easy Maintenance
  • Speed up the development
  • Two-Way Data Binding
  • Model-View-Controller (MVC)

Easy Maintenance: AngularJS provides ease of maintenance along with fast and simple web applications, as it holds power-packed features like Directives, Animations, Data Binding, Routing, Form Validation, API Client, and etc.

Speed up the development: It took less time and effort to develop the application. The code of data binding and data server can be written in few lines.

Two-Way Data Binding: One of the core features of AngularJS which makes it popular is two-way data binding. Any changes to the model are immediately reflected in the View, and any changes in the View update the model in two-way data binding.

Model-View-Controller (MVC): MVC stands for Model View and Controller. It is a software design pattern used for the development of web applications.

What is ReactJS?

ReactJS is the most commonly used front-end JavaScript library for building user interfaces or UI components, it is created by Facebook. ReactJS has become highly popular because of its simplicity and flexibility. React can be used as a base to develop single-page or mobile applications.

Advantages of ReactJS:

  • Ease of learning
  • Great Developer Tools
  • Reusable Components

Ease of learning: When compared to Angular, is easier to grasp. There is a wide range of tutorials and learning resources available online. Anyone with a Java background will be able to grasp ReactJS quickly.

Great Developer Tools: React tools helps you design and debug the technology. The tools are available for Firefox and Chrome browsers. Moreover, the tools enable you to monitor the component hierarchy in the virtual DOM.

Reusable Components: ReactJS is entirely built on components. Each component has its own set of features and controls its own execution. You can reuse code, making app development easier to maintain. The reusable code can also support you in maintaining a consistent look throughout all projects.


AngularJS vs. ReactJS Comparison



AngularJS: AngularJS is a structural framework for developing dynamic web apps.

ReactJS: ReactJS is a JavaScript library that allows you to build UI components.

Learning curve

AngularJS: For beginners, learning Angular is difficult.

ReactJS: When compared to Angular, is easier to grasp.

Community support

AngularJS: It has a strong and dependable community support system.

ReactJS: When it comes to community support React doesn’t offer much.

Testing & Debugging

AngularJS: A single tool can handle all of the testings and debugging for an entire project.

ReactJS: It requires a set of tools to perform different types of testing.


AngularJS: It is based on Virtual DOM

ReactJS: Based on MVC (Model View Controller)

Written in

AngularJS: AngularJS is based on Typescript

ReactJS: ReactJS is based on Javascript

Data Binding

AngularJS: AngularJS uses two-way data binding

ReactJS: ReactJS uses one-way data binding

Which is better?

In terms of single-page applications, both ReactJS and AngularJS are excellent choices. ReactJs is simple to grasp and use, however, AngularJs is more difficult to grasp and use due to third-party libraries and syntax. ReactJS works on Virtual DOM while AngularJs works on Regular DOM.
