One of React’s key features is its Virtual DOM (Document Object Model). Instead of directly manipulating the real DOM, React creates a virtual representation of it, allowing for efficient updates and minimizing performance bottlenecks. When data changes in a React application, the library intelligently updates only the necessary parts of the virtual DOM and then efficiently applies those changes to the real DOM. This approach results in a smoother and more responsive user experience.
React is often used in conjunction with other tools and libraries, such as Redux for state management and React Router for handling navigation. Additionally, it can be integrated with backend technologies and APIs to build full-stack applications. React’s strong community support, extensive ecosystem, and the ability to build both single-page applications (SPAs) and server-rendered applications make it a popular choice for modern web development.
