React
JavaScript library for building user interfaces.
React is a popular JavaScript library developed by Facebook for building dynamic, component-based user interfaces for web and mobile applications. Its declarative approach and virtual DOM enable developers to create fast, interactive frontends with reusable components, streamlining development and maintenance. React’s ecosystem, including tools like Redux and Next.js, supports complex state management and server-side rendering, making it suitable for startups building performant, scalable products. With a vast community and rich resources, React is a top choice for creating engaging user experiences.
