React.js, developed by Facebook, is a JavaScript library that revolutionizes the way we build user interfaces. Known for its component-based architecture and virtual DOM, React enables the creation of dynamic, efficient, and responsive web applications. With its declarative syntax and reusable components, React has become a go-to choice for modern, interactive web development.
