React Compiler deep dive
summary
React Compiler claims to avoid re-rendering values and components that don’t depend on changed state by statically analyzing code using React’s rules and heuristics inspired by V8’s approach It detects purity violations and skips compiling those components, recommends using useSyncExternalStore for external subscriptions, enforces treating props as immutable and avoiding post JSX mutation, and demonstrates that when components follow the rules the compiler can automatically emit faster updates with no runtime correctness regressions
