Facebook React

Facebook React is a JavaScript library used to build user interfaces, especially for websites and apps. It allows developers to create reusable components—like buttons or forms—that update dynamically without needing to reload the whole page. React's efficient rendering updates only the necessary parts of a webpage when data changes, making user interactions smooth and fast. It’s widely adopted because it simplifies complex UI development, improves performance, and helps maintain organized, modular code. Overall, React enhances the user experience by delivering responsive and interactive digital interfaces efficiently.
