How does it handle the migration from class components to hooks?

The skill provides a side-by-side mapping of legacy state and lifecycle methods (like componentDidMount) to their modern Hook equivalents (useState, useEffect).

Is TypeScript migration included in this skill?

Yes, it offers specific patterns for adding types to existing JavaScript components, including interfaces for Props and generic types for reusable components.

Can this skill help with React 18's new concurrent features?

Yes, it provides implementation patterns for Transitions, Suspense for data fetching, and the new Root API introduced in React 18.

Does it support automated code refactoring?

It includes specific instructions and scripts for running React codemods to automate the renaming of unsafe lifecycle methods and the conversion of JSX transforms.
