React has dominated frontend development since its release. Created by Jordan Walke at Facebook (now Meta) and first deployed on Facebook’s News Feed in 2011, it was open-sourced in 2013 and quickly became the most popular library for building user interfaces on the web.
React’s core idea — a component-based architecture with a virtual DOM for efficient rendering — was controversial when it launched. Mixing HTML-like syntax (JSX) directly in JavaScript code went against prevailing best practices, but developers found it incredibly productive once they got used to it. The component model made it natural to build complex UIs from small, reusable pieces.
The introduction of Hooks in React 16.8 (2019) was a game-changer, letting developers use state and other React features without writing class components. This simplified the mental model and made code more reusable. Today, functional components with hooks are the standard way to write React.
React’s ecosystem is massive. React Native extends the model to mobile app development for iOS and Android. Next.js (by Vercel) has become the most popular React framework for production applications. The npm registry shows React is downloaded over 20 million times per week.
In 2024-2025, React Server Components have been a major focus, allowing components to render on the server and send minimal JavaScript to the client. This represents a significant shift in how React applications can be architected, blending server and client rendering more fluidly.
Meta continues to develop React with a dedicated team, and the project has thousands of contributors. While Vue.js, Svelte, and Angular all have their strengths, React’s combination of a vast ecosystem, huge community, job market demand, and continuous innovation keeps it as the default choice for most new web projects.
