Does it support React 18 concurrent features?

Absolutely. It includes implementation patterns for the New Root API, automatic batching, Suspense for data fetching, and the useTransition hook.

Can I use it to move my project to TypeScript?

Yes, the skill provides patterns for converting JavaScript components to TypeScript, including defining prop interfaces and handling generic components.

Does this skill help with performance optimization?

Yes, it offers best practices for implementing useMemo, useCallback, React.memo, and code splitting to reduce unnecessary re-renders and improve load times.

Can this skill handle large-scale React migrations?

Yes, it utilizes automated codemods and incremental migration strategies to handle large codebases safely by breaking down the process into manageable steps.

How does it help with class component migration?

It provides logic to map state, lifecycle methods (componentDidMount, etc.), and context consumers directly into their functional equivalents using hooks.
