React

React is a JavaScript library for building user interfaces through a component-based architecture. Developed and maintained by Meta, it enables developers to create dynamic, high-performance web applications by composing reusable components that manage their own state and render efficiently through a virtual DOM that minimizes actual DOM manipulations.

The ecosystem around React is extensive. React Router handles navigation. State management options range from built-in Context API and useReducer to external libraries like Redux, Zustand, and Jotai. Server-side rendering and static generation are available through Next.js and Remix. React Native extends the component model to iOS and Android mobile development. The hooks API, introduced in React 16.8, simplified state management and side effects within functional components.

For web development teams, React is the most widely adopted frontend library, which translates to practical advantages: the largest talent pool, the most third-party components and libraries, and the most comprehensive documentation and community resources. React Server Components, introduced with React 18 and fully supported in Next.js, represent the latest evolution, allowing components to run on the server to reduce client-side JavaScript while maintaining the component-based development model.
