ReactJs is the most popular web development JavaScript front-end library. React is a library of JavaScript to build UIs. Facebook developed ReactJs. It can be used to manage the web and mobile applications view layer. We can develop reusable UI components with ReactJs.

Advantages of React
Easy dynamic application building: React makes dynamic web apps easier to build since it takes less writing and provides more functions, rather than JavaScript.

Reusable: Components are the building elements of any React application and generally numerous components are composed in a single app. These components are logical and controlled and may be reused throughout the application, which substantially lowers the development time of the application.

Small learning curve: React is easy to learn because it usually brings together some helpful additional fundamental HTML and JavaScript concepts.

Performance improvement: React utilizes Virtual DOM to create web apps quicker. Instead of updating all components again like traditional Web applications, Virtual DOM merely compares the component status and actualization of the preceding items in the Real DOM.

Features of React
Components
ReactJS is a multi-component application and every component having its own logic and controls.

JSX
JSX stands for JAVAScript XML. It extends the ES6 to coexist with Javascript react code, which is HTML-like text. 

One-way Data Binding
ReactJS is developed such that unidirectional data flow or one-way data binding is followed. The advantages of single-way data binding provide better control over the whole application. Flux is a design that helps maintain the unidirectionality of your data.

Simplicity
ReactJS utilizes a JSX file that simplifies and codes the application and understands it.

Virtual DOM
A virtual DOM object is the original DOM object representation. It acts as a uniform data connection. When changes occur in the Web app, the whole user interface is displayed in the virtual DOM display. The difference between the prior DOM and the new DOM is then checked. Once done, only items that have really changed are updated by the real DOM.

Performance
This is due to the fact that a virtual DOM is managed. The Document Object Model is a cross-platform and programming API that deals with HTML, XML, or XHTML.
