How does it handle large-scale refactoring tasks?

The skill utilizes jscodeshift and specific React codemods to automate repetitive transformations across entire directories efficiently.

Is TypeScript migration part of the modernization process?

Yes, the skill includes templates and patterns for converting JavaScript components to type-safe TypeScript interfaces and generics.

Does this skill support the React 18 upgrade path?

Yes, it includes specific guidance for the New Root API, automatic batching, and concurrent features like Transitions and Suspense.

Can it automatically convert class components to functional hooks?

It provides the logic and codemod configurations to transform state, lifecycle methods, and context consumers into their modern hook equivalents.

Does it help with performance optimization during migration?

Absolutely. It offers patterns for useMemo, useCallback, and React.memo to prevent unnecessary re-renders in modernized components.
