What are React codemods?

Codemods are automated scripts that refactor large codebases quickly, such as renaming unsafe lifecycle methods or updating to the new JSX transform (React 17+).

Does this skill support React 18 upgrades?

Yes, it includes specific guidance for moving from React 16 and 17 to React 18, including the new Root API, automatic batching, and concurrent features.

How does it improve application performance?

It guides users in implementing React.memo, useMemo, and useCallback correctly, as well as leveraging React 18's non-blocking transition API.

Does this skill help with TypeScript migration?

Yes, it includes patterns and checklists for adding type safety to your React components and props during the modernization process.

Can it help convert Class components to functional Hooks?

Absolutely. It provides patterns for converting state, lifecycle methods, and context consumers into functional components using useState, useEffect, and useContext.
