What Is React?

React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It lets you compose complex UIs from small and isolated pieces of code called “components”.

What is React used for?

React is used for frontend web apps to detect user input, fetch data, and update the user interface with data. React does all this with maximum performance and flexibility.

Why is React popular?

React initially skyrocketed to fame because it made fetching and showing data in your JavaScript apps much easier than before. Because React is just a library instead of an elaborate framework, it was and still is relatively easy to learn.
