Angular JS vs React JS

In the current era, we see a rapid increase in the tools and technologies frameworks for developing and deploying applications. Each framework holds its importance. AngularJS and ReactJS are two frameworks designed for efficient development of the front end. Choosing the right framework is one of the essential tasks. Many of us are confused about choosing the best among AngularJS and ReactJS. This blog will discuss ReactJS, AngularJS, features, and many more differences between them. Due to the high popularity of these frameworks, there is a high demand for opportunities in the front-end development field. AngularJS training and ReactJS training sessions will help you master the concepts and gain exposure to real-time projects, nurturing you to clear the certification exams. Let's get started!

What is ReactJS?

React is a front-end javascript-based library that helps build user interfaces from reusable user interface components. It provides the flexibility for the users to create complex and seamless user interfaces.

ReactJS was developed by a software programmer at Facebook and later has been implemented in other products. ReactJS makes use of server-side rendering, which helps in delivering a performance-oriented solution. It is responsible for developing just the view layer of an application. ReactJS includes two main components that define the HTML code you would like to see in the UI and the HTML document in which all the components are rendered.

What is AngularJS?

AngularJS is an open-source framework that is used for the development of dynamic applications. In AngularJS, the developers are allowed to make use of HTML as a template language.

AngularJS was first developed by Google and has become one of the most popular frameworks in the last few years. It also provides support for the MVC programming structure. AngularJS also offers data binding. In AngularJS, the developers use the HTML syntax for expressing the components that are in the application.

ReactJS vs AngularJS - Key Factors Comparison

1. Technology type

  • ReactJS: ReactJS uses the javascript library, which helps develop the view using MVC. ReactJS needs flux for the implementation of the architectural process.
  • AngularJS: AngularJS uses the complete MVC framework written in the Javascript language.

2. Architecture

  • ReactJS: ReactJS uses the component-based architecture using Javascript.
  • AngularJS: AngularJS uses the component-based architecture with a change in the technology stack - Typescript for AngularJS.

3. Languages used

  • ReactJS: Javascript E6+ language and JSX script are used in ReactJS. JSX is an extension of the syntax that looks in a way similar to HTML.
  • AngularJS: Typescript is used in AngularJS. Typescript is basically a superset of javascript. It helps in determining the typos easily, and coding is easy as well for easy navigation.

4. Debugging & Testing

  • ReactJS: ReactJS will need a certain set of tools for performing the testing and its types.
  • AngularJS: AngularJS will only need a single tool to perform the project's testing and debugging processes.

5. Data binding

  • ReactJS: In ReactJS, it is not possible to make changes to the UI elements without updating the corresponding model state. Hence it supports and uses only one-way data binding.
  • AngularJS: In AngularJS, the model state changes when there are any changes in the UI elements. Hence, it supports two-way data binding.

6. Latest version

  • ReactJS: The latest version of ReactJS is React 16. 8.6, which was introduced in the year 2019.
  • AngularJS: The latest version of AngularJS is Angular 1.7.8 which was introduced in the year 2019.

7. Rendering

  • ReactJS: It allows server-side rendering.
  • AngularJS: Angular provides client-side rendering.

8. Companies using

  • ReactJS: ReactJS is used by multiple companies like Netflix, Uber Technologies, Instagram, Pinterest, Facebook, etc.
  • AngularJS: Angular is used by different organizations like Beam, Streamline Social, Wepay, Mesh, Auto Trader, etc.

9. Licensing

  • ReactJS: MIT license is used in ReactJS.
  • AngularJS: MIT license is used in AngularJS, which is free of cost for commercial purposes.

10. Document object model

  • ReactJS: ReactJS uses a virtual DOM (document object model). React is capable of making changes only to a single element without the need to make changes to the complete tree structure through the virtual DOM.
  • AngularJS: AngularJS uses the real DOM which needs the complete tree structure to be updated whenever there is a change that takes place in Angular.

11. Speed and productivity

  • ReactJS: There is a lag identified when ReactJS works with redux.
  • AngularJS: The speed and productivity levels are high in Angular when compared with ReactJS.

12. Dependencies

  • ReactJS : ReactJS needs additional tools for dependency management.
  • AngularJS: There is no need for additional tools for dependency management in Angular.

13. Performance

  • ReactJS: The performance is fast as React uses virtual DOM.
  • AngularJS: The performance is low when compared with React.

14. Routing

  • ReactJS: ReactJS does not provide support for routing.
  • AngularJS: AngularJS makes use of the controllers or the templates for the router configurations.

15. Suitable for

  • ReactJS: ReactJS is best suitable for the development of single-page applications which requires an update of multiple views at the same time.
  • AngularJS: AngularJS is best suitable for the development of single-page applications which require an update of a single view at the same time.
