React.js is a JavaScript library developed by Facebook for building interactive user interfaces, particularly for single-page applications. It follows a component-based architecture, allowing developers to create reusable UI components. React employs a declarative approach, making it easier to develop, debug, and maintain applications efficiently. It is widely used in front-end development due to its flexibility and performance optimization techniques.

A key advantage of React is its Virtual DOM mechanism, which enhances performance by updating only the changed elements instead of re-rendering the entire DOM. React also supports JSX, a syntax extension that allows developers to write UI components using an HTML-like syntax within JavaScript. With features like hooks, state management, and integration with libraries like Redux, React remains a preferred choice for modern web development.
