React

It is a JavaScript framework that allows you to quickly and efficiently create user interfaces by including Java files in your HTML. You can also describe it as a Java library that you can use to create different UI through different components that help build and define your application’s structure.

To further explain it, REACT acts as the visible part of your application, it only manages symple data to know how your application will look to the public.

React helps you create interactive user interfaces easily. Design simple views for each state in your app, and React will efficiently update and render the correct components when the data changes.

Create encapsulated components that handle their own state, and turn them into complex user interfaces. Since the component logic is written in JavaScript and not templates, you can easily pass data through your application and keep state outside of the DOM.
