Modern React
summary
Covers concrete APIs and behaviors: createPortal renders children outside parent and still propagates events and context with examples (astronaut rendered on Mars, portal can create its own container or a new window), explains Concurrent Mode’s fiber time‑slicing and why components can throw promises, shows Suspense + lazy for code and react cache for data to avoid multiple spinners, and outlines hooks (useState/useEffect/useRef/useCallback) with pitfalls like stale closures and order dependence. Unstable APIs are flagged and practical tradeoffs are given.
