React.js is a popular JavaScript library for building user interfaces, particularly single-page applications (SPAs). It provides a component-based architecture and a virtual DOM, enabling efficient rendering and seamless user interactions. React simplifies the development of dynamic and responsive web applications by allowing developers to manage application state effectively. It is widely used to create modern web applications with reusable UI components.
