Facebook (for React)

React is a JavaScript library developed by Facebook that helps developers build interactive and dynamic user interfaces for websites and applications. It allows parts of a webpage to update efficiently without needing to reload the entire page, improving performance and user experience. React uses components—self-contained, reusable pieces of code—that can manage their own state, making complex interfaces easier to develop and maintain. Popularized by Facebook, React is widely adopted for creating fast, scalable, and maintainable front-end applications across various industries.
