What React is
React is the UI library that made component-based rendering the default mental model for front-end work, and the one whose conventions the rest of the ecosystem is written against. The last few years have been a significant shift: Server Components move part of the tree to the server, the compiler removes most manual memoisation, and Suspense and transitions have become load-bearing rather than optional. That shift has been contentious, partly because it makes framework choice inseparable from library choice — plain React on Vite is a different product from React inside Next.js. It competes with Vue and Svelte on developer experience, Solid and Preact on runtime cost, Angular in enterprise settings, and increasingly with the argument that a server-rendered application with a sprinkling of interactivity did not need any of this. Its ecosystem size remains the deciding factor for most teams.
