About React
React is a JavaScript library for building user interfaces, developed and maintained by Meta (Facebook). First released in 2013, React introduced a component-based architecture and virtual DOM diffing that transformed web development. Instead of manipulating the DOM directly, React developers build reusable UI components that re-render efficiently when state changes. React's one-way data flow and JSX syntax (JavaScript + HTML) made it the most popular frontend framework in the world, used by Facebook, Instagram, Netflix, Airbnb, Uber, and hundreds of thousands of applications. React 18 (2022) introduced concurrent rendering, automatic batching, and Suspense for data fetching. React Server Components (RSC), pioneered by Next.js, allow components to render on the server, reducing client bundle sizes. The React ecosystem is vast: Next.js for SSR/SSG, Remix for full-stack, Redux/Zustand/Jotai for state management, React Query/SWR for data fetching, and Tailwind/styled-components for styling. According to Stack Overflow surveys, React has been the most used web framework every year since 2019. React Native extends the model to mobile, sharing business logic across iOS and Android. React's main criticisms are its steep learning curve for newcomers and the decision fatigue from choosing among dozens of ecosystem libraries for each concern.
Frequently Asked Questions
Is React a framework or a library?
React is officially a library focused on building UI components. Unlike Angular (a full framework), React handles only the view layer — you assemble the rest (routing, state, data fetching) from separate ecosystem packages.
Should I learn React in 2025?
Yes. React remains the most in-demand frontend skill in job listings by a wide margin. Next.js (built on React) is the dominant full-stack framework for JavaScript. Learning React opens doors to web, mobile (React Native), and desktop (Electron) development.
React vs Vue — which is better for beginners?
Vue has a lower initial learning curve with its Options API and single-file components. React requires understanding JSX, hooks, and assembling an ecosystem stack. However React's dominance in the job market makes it the better career investment despite the steeper entry.
