Difference Between ReactJS And AngularJS


Choosing the right framework for a new JavaScript system, application, or website is the top priority now-a-days. It can have a direct effect on a project’s durability, ability to fit in deadlines, further code maintainability, and scalability of your future app. Angular and React are two new web technologies on the rise. Many business owners, technical decision makers, and project managers are having difficulties about making a choice between these two. The amount of JavaScript tools is steadily increasing, turning the selection of appropriate technology into a challenge. While among the top discussions is AngularJS vs. ReactJS, both are highly-performing, advanced, and widely used worldwide.

Let us take a close look on the world-wide popularities of both, Angular and React .




Let us have a quick overview of the attributes in both the frameworks.

AngularJS is developed with the primary purpose of addressing single page application development. AngularJS works with MVC platform, where it simplifies development by providing a reliable solution. AngularJS follows some guidelines, like Angular data binding. In Angular, the Model and the View are linked to allow automatic data synchronization between the two.

Let us see some advantages of AngularJS.

  • Complete Framework

AngularJS is complete framework that can run in any browser or platform. Angular is consistent, overwhelmed with ready-made tools, ng components are robust and quite mature, as contrasted with React.

  • Two-Way Data Binding

This property is probably the top feature of AngularJS, as it diffuses the impact after every minor data change and does way with the need for further effort with data sync in View and Model.

  • Architecture

AngularJS has a component-based architecture. Components have deep binding and each of them comprise of elements with only relevant functionality. They are loosely coupled and properly encapsulated. Such approach makes components easily re-usable, enhance their testability and further maintainability.

Disadvantages of AngularJS

Steep learning curve and complexity are main weak points of AngularJS. Like any other client-side rendering technology in JavaScript framework comparison list, programmers should place special emphasis on security to make apps reliable and safe.

React JS

ReactJS provides us high performance client and server side rendering with a one-way flow for data binding. ReactJS is based on building reusable components of code base which make an app very lightweight, more of a library that makes it quite easy to work with.

React is more of a library than a framework. It can best be described as an application view that allows the programmer to utilize reusable components again and again. It is composed of its own React libraries, tools, and solutions that developers can use to build their own JS framework.

Let us see the advantages of React JS.

  • JSX Syntax

JSX is a JS syntax that allows developer to use HTML quotes and usage of HTML tag syntax for subcomponents rendering. It promotes building of machine-readable code and provides ability to compound components in one compile-time verified file.

  • Rendering

Rendering is the best features of React that gives a significant edge over Angular. The technology comprises smart methods to mitigate the amount of DOM operations, optimize and accelerate the updates process. Virtual DOM is of great use while handling vast databases.

Disadvantages of React JS

ReactJS is not a full-scale framework and for this very reason integration of the UI library into a common MVC framework requires good programming knowledge.

So, after this complete discussion, we can’t say which is better - ReactJS or AngularJS. Both technologies are the best at their prospective purpose. Depending upon custom app goal, we can use any one. Angular usually assumes the creation of core skeleton for a front-end app, whereas React.js can be applied to improve its specific parts.
