React is a JavaScript library used to build user interfaces for both web and native applications. React allows developers to create components, which are reusable pieces of code that can be combined to form entire applications. These components are written using JSX, a JavaScript extension that allows for declarative markup. React also focuses on interactivity, allowing for dynamic updates to the user interface based on user input. Beyond its core functionality, React has a vast ecosystem of supporting tools and frameworks, including Next.js and Remix, which facilitate the development of full-stack applications. Additionally, React has a large and active community of developers who contribute to its development and provide support to others.
