ReactJS is an open source JavaScript library designed by Facebook for creating well structured, scalable and reusable web apps fast. The core objective of ReactJS is providing the best possible rendering performance. It also provides a facility to create reusable UI components. The strength of ReactJS comes from the focus on individual components instead of working on the entire web app.

Importance of React Js:

It uses JSX (a unique syntax that allows HTML quotes as well as HTML tag syntax application for rendering specific subcomponents) which is very helpful in promoting the construction of machine-readable codes and at the same time compounding components into a single-time verifiable file.
React JS is a JavaScript library that lets you create high-performance, innovative user interfaces using reusable components. React JS is officially maintained by Facebook and Instagram, but it has a vibrant developer community that contributes to the codebase.

ReactJS is one of the most trending front end frameworks these days. Many developers have been using this library to build user interfaces. ReactJs ...
... allows developers to create large Scale web applications that can change data, without reloading the page. The major objective of React is to be fast, scalable and simple. It can be used with a combination of JavaScript libraries or frameworks, such as Angular JS in MVC.

ReactJs Framework is a declarative, efficient, and flexible open-source JavaScript library for building simple, scalable, and fast frontends of web applications. React brings innovations to the world of JavaScript by creating a virtual DOM that can render your application faster than the browser while remaining small enough to encourage reuse.

Features of React Js-

React.js is declarative
React.js is Simple
React Js is component based and extensive framework
React Js supports server side rendering
React Js is fast and easy to learn.

JSX- React uses a markup language called JSX to bind the user interface. This allows you to write the components in a more human-readable format and compile them into regular JavaScript code.

React Native- The React Native framework combines the power and familiar design of React, with the flexibility of native device components. It’s engineered by Facebook and Instagram to be made of pure Javascript and it uses the same fundamental UI building blocks as regular iOS and Android apps. The best part of the React Native framework is that it allows/admit components written in Objective-C, Java or Swift.

Single-Way data flow- It is known that React uses a virtual DOM to manipulate the data and display them in a different manner. The interaction between user and our application is handled by using observables that are handled both at nature level as well as the state level. Code bases are written in jsx which allows us to write JavaScript code and after compiling it converts into normal JavaScript (JS) code.

Virtual Document Object Model- A React component receives its properties as HTML attributes. It cannot directly modify the properties passed to it, but can pass call back functions through props in its HTML tags. Upon receiving this call back function, we can do modifications on that particular property which is passed as an attribute. This complete process is known as "properties flow down; actions flow up".

Advantages of ReactJS-

1.Speed- React allows developers to utilize individual parts of their application on both client-side and server-side in order to optimize the development process while maintaining a seamless experience for the users, including the most popular social media website Facebook.

2.Flexibility- React has been a staple in frontend frameworks for quite some time. Compared to other frontend frameworks, the React code is easier to maintain and is flexible due to its modular structure.

3.Performance- React JS was built by Facebook to provide a view layer for web applications. The core of the library offers a virtual DOM and server-side rendering, which allows complex applications to run at a high frame rate.

4.Intuitive- ReactJS is a UI library which is extremely intuitive to work with. It enables fast and quality assured application development that, in turn, saves time for both - clients and developers. The app developed using ReactJS technology is interactive and provides great user experience.

5.Declarative- ReactJS is a JavaScript library developed and maintained by Facebook to create UI components. It allows data changes that trigger automatic alterations in the selected parts of user interfaces. Not only does this device have a good interface that is well suited for different users, it also has a progressive functionality. This means that there is no additional function that you need to perform in order to update the user interface.

6.Provides Reusable Components- ReactJS is a JavaScript library that helps in building scalable and reusable web applications. It lets the developers reuse components by creating a new application and thereby reducing their development efforts. ReactJS is lightweight and it ensures optimum performance for all the applications.

7.JavaScript library- The JS library consists of several functions including one that converts the HTML components into required functions and transforms the entire project so that it is easy to understand. A strong blend of JavaScript and HTML syntax is always used, which automatically simplifies the entire process of writing code for the planned project.

8.Components Support- ReactJS is a JavaScript framework which helps to deal with the interactions between components. It is known as a reactive programming library which clearly represents the model-view-controller paradigm and assists to solve multi-level problems in an efficient way. The JS codes are used for creating reusable UI components that work with virtual DOM written in JSX format.

9.SEO-friendly- ReactJS is the first library to enable developers to create SEO-friendly, energy-efficient UX on the web. With React's virtual DOM and innovative, reactive programming paradigm, developers get the best performance by building apps that scale seamlessly.

10.Proficient Data Binding- A one-way data flow in ReactJS. It is very easy to use and it is simple. This flow has two-way data binding which is a rare feature for an open source library or language.
