React Today and Tomorrow
summary
React adds "hooks": functions like useState and useEffect (and useContext) that let function components hold state, perform side effects, and subscribe to context without classes. The proposal is additive and opt‑in (alpha shipped in v16.7), aims to eliminate wrapper‑hell and tangled lifecycle logic by enabling custom hooks, and runs in production at Facebook for about a month with no major bugs reported. The team backs numbers — npm downloads +70% YoY and 1.25M React DevTools installs — and the live demo works.
