About React
React is an open-source JavaScript library maintained by Meta and the community for building interactive user interfaces through a component-based architecture. It uses JSX syntax, a virtual DOM for efficient rendering, and supports both client-side and server-side rendering. As of 2026, React 19 is the stable release, with the React Compiler becoming standard practice to automate performance optimizations previously requiring manual memoization. React Server Components are now production-standard, enabling server-driven data fetching within the component model.
