What is React?

React is an open-source JavaScript library used for building user interfaces. It was created by Facebook and has since been adopted by many other companies and developers worldwide. React allows developers to create reusable UI components and efficiently update and manage the state of their application. It is known for its simplicity, performance, and flexibility, making it a popular choice for web development.
