React

React is a popular open-source JavaScript library developed by Meta (formerly Facebook) for building fast, interactive user interfaces. Based on a component-driven architecture and a virtual DOM, React enables efficient rendering and a smooth user experience. It's widely used for building single-page applications (SPAs), mobile apps (via React Native), and dynamic web interfaces. React promotes reusability, scalability, and easy maintenance, making it a favorite among developers for modern front-end development. With strong community support, vast resources, and seamless integration with other tools, React powers some of the world’s most dynamic web applications.
