React.js<\/a>\u00a0was released by a software engineer working for Facebook \u2013 Jordane Walke in 2011.\u00a0React<\/a>\u00a0is a\u00a0JavaScript<\/a>\u00a0library<\/a>\u00a0focused on creating declarative user interfaces (UIs) using a component-based concept. It\u2019s used for handling the view layer and can be used for\u00a0web<\/a>\u00a0and mobile apps. React\u2019s main goal is to be extensive, fast,\u00a0 declarative, flexible, and simple.\u00a0<\/p>

React is not a framework, it is specifically a library.\u00a0 The explanation for this is that React only deals with rendering UIs and reserves many things at the discretion of individual projects. The standard set of tools for creating an application using ReactJS is frequently called the\u00a0stack<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Now, the main question arises in front of us is why one should use React. There are so many open-source platforms for making the front-end web application development easier, like Angular. Let us take a quick look on the benefits of React over other competitive technologies or frameworks. With the front-end world-changing on a daily basis, it\u2019s hard to devote time to learning a new framework \u2013 especially when that framework could ultimately become a dead end. So, if you’re looking for the next best thing but you’re feeling a little bit lost in the framework jungle, I suggest checking out React.<\/div>
\u00a0<\/div>

1. Simplicity<\/em><\/h3>
\u00a0<\/div>
ReactJS is just simpler to grasp right away. The component-based approach, well-defined lifecycle, and use of just plain JavaScript make React very simple to learn, build a professional web (and mobile applications), and support it. React uses a special syntax called JSX which allows you to mix HTML with JavaScript. This is not a requirement; Developer can still write in plain JavaScript but JSX is much easier to use.<\/div>
\u00a0<\/div>

2. Easy to learn<\/em><\/h3>
\u00a0<\/div>
Anyone with a basic previous knowledge in programming can easily understand React while Angular and Ember are referred to as \u2018Domain-specific Language\u2019, implying that it is difficult to learn them. To react, you just need basic knowledge of CSS and HTML.<\/div>
\u00a0<\/div>

3. Native Approach<\/em><\/h3>
\u00a0<\/div>
React can be used to create mobile applications (React Native). And React is a diehard fan of reusability, meaning extensive code reusability is supported. So at the same time, we can make IOS, Android and Web applications.<\/div>
\u00a0<\/div>

4. Data Binding<\/em><\/h3>
\u00a0<\/div>
React uses one-way data binding and an application architecture called Flux controls the flow of data to components through one control point \u2013 the dispatcher. It’s easier to debug self-contained components of large ReactJS apps.<\/div>
\u00a0<\/div>

5. Performance<\/em><\/h3>
\u00a0<\/div>
React does not offer any concept of a built-in container for dependency. You can use Browserify, Require JS, EcmaScript 6 modules which we can use via Babel, ReactJS-di to inject dependencies automatically.<\/div>
\u00a0<\/div>

6. Testability<\/em><\/h3>
\u00a0<\/div>
ReactJS applications are super easy to test. React views can be treated as functions of the state, so we can manipulate with the state we pass to the ReactJS view and take a look at the output and triggered actions, events, functions, etc.\u00a0<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

JSX<\/h3>

JSX stands for JavaScript XML. It is a JavaScript syntax extension. Its an XML or HTML like syntax used by ReactJS. This syntax is processed into JavaScript calls of React Framework. It extends the ES6 so that HTML like text can co-exist with JavaScript react code. It is not necessary to use JSX, but it is recommended to use in ReactJS.<\/p>

Components<\/h3>

ReactJS is all about components. ReactJS application is made up of multiple components, and each component has its own logic and controls. These components can be reusable which help you to maintain the code when working on larger scale projects.<\/p>

One-way Data Binding<\/h3>

ReactJS is designed in such a manner that follows unidirectional data flow or one-way data binding. The benefits of one-way data binding give you better control throughout the application. If the data flow is in another direction, then it requires additional features. It is because components are supposed to be immutable and the data within them cannot be changed. Flux is a pattern that helps to keep your data unidirectional. This makes the application more flexible that leads to increase efficiency.A virtual DOM object is a representation of the original DOM object. It works like a one-way data binding. Whenever any modifications happen in the web application, the entire UI is re-rendered in virtual DOM representation. Then it checks the difference between the previous DOM representation and new DOM. Once it has done, the real DOM will update only the things that have actually changed. This makes the application faster, and there is no wastage of memory.<\/p>

Simplicity<\/h3>

ReactJS uses JSX file which makes the application simple and to code as well as understand. We know that ReactJS is a component-based approach which makes the code reusable as your need. This makes it simple to use and learn.<\/p>

Performance<\/h3>

ReactJS is known to be a great performer. This feature makes it much better than other frameworks out there today. The reason behind this is that it manages a virtual DOM. The DOM is a cross-platform and programming API which deals with HTML, XML or XHTML. The DOM exists entirely in memory. Due to this, when we create a component, we did not write directly to the DOM. Instead, we are writing virtual components that will turn into the DOM leading to smoother and faster performance.<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
