React encourages on creating reusable components. It offers a simple model and provides better performance. It has a strong client base and a large community. It has very proper documentation. It can also render the server side code using Node. It implements the one-way reactive data flow. Hence, it is way beyond the traditional way of data binding.

Features: Here is a list of impressive features ReactJS possess.

    • React Native:

React includes the react libraries. They provide the react architecture to the native applications such as Android and iOS.

    • Components:

    • JSX:

JSX is a JavaScript which uses the HTML tags and syntax to render the components. It is then processed into the JavaScript function calls of this framework.

    • One-Way Reactive Data Flow and Flux:

Flux is a pattern that keeps your data flow unidirectional. React follows the one-way data flow to process your code.

    • Virtual DOM (Document Object Model):

This is a unique feature of React. React creates a data structure which is stored in internal memory. It is stored as cache. This feature enables the natural rendering of the page and components.

    • License:

React is a licensed product of Facebook Inc. Everything is licensed under its parent company.
