A popular type of framework for building responsive web applications is React. React is a JavaScript library for constructing user interfaces, allowing developers to create reusable UI components that update efficiently as the data changes. Its component-based architecture supports a responsive design, adapting seamlessly to various screen sizes and devices. Additionally, React’s virtual DOM enhances performance, making it suitable for dynamic applications. By efficiently managing changes to the web interface, React simplifies building complex and interactive applications, promoting a better user experience overall.
