What is React JS..?

Technology / September, 18 2019


ReactJS is an open-source JavaScript library for building user interfaces. It is currently one of the most popular JavaScript libraries in the IT field and it has a strong foundation and large community behind it.

React JS is a Javascript framework which is used for simplifying the process of front end web development. If you learn ReactJS, you need to have knowledge of JavaScript, HTML5 and CSS.

React creates an in-memory data structure cache which computes the changes made and then updates the browser. This allows a special feature which enables programmers to code as if the whole page is rendered on each change whereas react library only render components which actually change. Its main goal is to be fast, simple and scalable.

#ReactJS Or AngularJS Comparison: Which is Better..?

What is React JS

AngularJS and ReactJS have been on a see-saw ride to the top for the advancement of forefront Mobile and Web Applications. With a developing library and dynamic networks, both of the frameworks continue offering more up to date forms all the time.

When it comes to selecting an appropriate JavaScript framework for the development of an exceptional web application, the developers have precisely got many options available.

They include AngularJS, ReactJS, etc. However, it rather becomes a tricky decision for the developers as each of these frameworks have their pros and cons.

React vs Angular comparison: library against framework

Angular is one of the most popular javascript frameworks and like other similar software suits it offers multiple out-of-the-box solutions and designs. At a time when, React ecosystem comprises any number of composable, targeted online tools and ReactJS acts as one of the building blocks.

Advantages of angularjs

  • Global community support is one of the factors, that can easily make Angular the best javascript framework. Developers and designers constantly collaborate and contribute to the community, increasing credibility and reliability of the framework.
  • It is a full-fledged framework that can run in any browser or platform. Moreover, it is consistent, overwhelmed with ready-made tools, ng components are robust and quite mature, as contrasted with React.
  • Two-way data bind is probably the top feature, 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.

Given the fact that our company makes active use of ng2, it is essential to include react vs angular 2 comparison as well.

  • TypeScript is an enhanced JS super-set that supplies optional static type checking, object-based programming patterns, and high-performance typing features.
  • Owing to component-based architecture components have deep binding and each of them comprises elements with only relevant functionality. What is more, they are loosely coupled and properly encapsulated. Such approach makes components easily reusable, enhance their testability and further maintainability.

Advantages of ReactJS

  • JSX is a JS syntax that enables 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.
  • Prompt rendering is among 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 (Document Object Model) is of great use while handling vast databases.
  • The core difference between reactjs and angularjs is that React is JS-centric, while ng2 remains HTML-centric. JavaScript is far more robust, than HTML, that makes React far more simple, focused and consistent.


React and Angular offer completely diverse approaches to web application development for startup, small and midmarket businesses. Both technologies are powerful and flexible, while none of them is worse or better, than the other. Depending upon custom app goals and particular system constraints, developers can run from ng2 to React, and back.

Opting for Angular, it usually assumes the creation of core skeleton for a front-end app, whereas React.js can be applied to improve its specific parts. Moreover, it can be integrated with other frameworks, like Backbone or even well-known Angular.
