Which state management libraries are supported?

It includes implementation patterns for local state, the Context API, and popular external libraries like Zustand, Redux Toolkit, and TanStack Query.

Does it enforce specific coding standards?

Yes, it mandates the use of strict TypeScript, semantic HTML for accessibility, and proper cleanup of side effects to prevent memory leaks.

Does this skill support the latest React 19 features?

Yes, it specifically targets React 19 patterns including the use() hook, Server Components (RSC), useActionState, and modern form actions.

Can it help me optimize React app performance?

Absolutely. The skill provides guidance on memoization using useMemo and useCallback, code-splitting with Suspense, and identifying unnecessary re-renders.
