ReactJS Article

Introduction

ReactJS is a JavaScript library for building and managing user interfaces (UI) in web and mobile apps. It is maintained by Facebook and a community of individual developers and companies. React is Open Source.

React was created by Jordan Walke, a software engineer at Facebook. He was influenced by technologies such as PHP, HTML and XHP. It was first deployed on Faceboo's newsfeed in 2011.

Features

JSX - JSX is used for template creation instead of the usual JavaScript. JSX is a very simple JavaScript that permits HTML quoting. And using the HTML syntax, JSX helps to render subcomponents.

React Native - These libraries give the architecture of ReactJS to other native applications such as UPD, Android and IOS.

Virtual DOM - This can be used to create a unique data structure which helps to compute changes initiated as well as updating the browser. In addition, this offers a unique feature that enables programmers to code with ease. It is as if every web page is rendered by the React library with each change. Whereas in truth, only components that were actually changed are rendered.

State management, mobile application use, routing and interacting with an API.

Pros/Cons

ReactJS has its pros and cons:

Pros	Cons
SEO Friendly	View Orientated
Easily reuseable components	Requires more code in some cases
Easy to create UI test cases	Requires the manual processing of data changes
Debugging is relatively easy with browser extensions	Requires a lot of knowledge, especially in OO Programming concepts and JS

Extra Programs

React Native (to help build native apps)
NodeJS (to help build web apps using a javascript engine)
JavaScript, HTML, CSS (Front-End languages to help make webpage content with ReactJS)
Redux (open source JS library for managing application state)

Summary

In conclusion:

ReactJS offers a way to create mobile apps in a clean, non-discriminative way (such as native applications and the Virtual DOM) this allows programmers to create functioning and smooth UIs using just one main language (JavaScript) as opposed to dozens of different languages. ReactJS is widely used in many applications and websites, including Skype, Facebook, Android and IOS.
