Future of React
summary
React 19 stays in RC while teams squash a few client‑suspense performance regressions; a new React Compiler runs on facebook.com and instagram.com, enabling measurable runtime and developer-efficiency wins and fixing a handful of end‑to‑end tests within hours. Server components and streaming land as stable primitives, built without shipping extra runtime, and work with Next.js/Vercel prototypes. Plans include React Compiler used on facebook.com, RC stage for React 19, server components (RSCs) stabilized, aiming for SWC interface
