What is ReactJS?

ReactJS, commonly referred to as React, is an open-source JavaScript library developed by Facebook for building user interfaces (UIs) for web applications. It allows developers to create reusable UI components and efficiently manage the state of their applications.

What are the key features of ReactJS?

Some key features of ReactJS include its component-based architecture, virtual DOM (Document Object Model), JSX syntax for combining JavaScript with HTML, and its focus on unidirectional data flow, which simplifies the process of building interactive user interfaces.
