ReactJS

React is a popular JavaScript library for building user interfaces. Developed by Facebook, it allows developers to create reusable UI components, manage the state of applications efficiently, and render views dynamically based on state changes. React's virtual DOM enhances performance by minimizing direct manipulations of the real DOM, leading to faster and more responsive applications. Its component-based architecture promotes modularity and code reuse, making it easier to manage large-scale applications. React is widely adopted in web development for its simplicity, flexibility, and robust ecosystem.
