How does it handle lifecycle method migration?

It provides direct logic mappings for converting lifecycle methods like componentDidMount, componentDidUpdate, and componentWillUnmount into the useEffect hook with appropriate dependency arrays.

Does it support migrating from JavaScript to TypeScript?

Absolutely. The skill provides patterns and interface definitions for converting standard JavaScript components into type-safe TypeScript (TSX) structures.

Does this skill provide performance optimization advice?

Yes, it identifies bottlenecks and suggests optimizations such as memoization with useMemo/useCallback and code splitting with React.lazy and Suspense.

Can it automate the refactoring process for large codebases?

The skill includes instructions and scripts for using jscodeshift and official React codemods to automate repetitive, large-scale code transformations safely.

Can this skill help with React 18 breaking changes?

Yes, it includes specific guidance for implementing the new Root API, handling automatic batching, and managing Strict Mode changes introduced in React 18.
