An infinite loop in useEffect occurs when dependencies are missing or unstable, triggering continuous re-renders. This Skill analyzes dependency arrays to identify missing dependencies and fix infinite loops caused by state updates inside the hook.

To fix missing dependencies in useEffect, you must add all referenced variables to the dependency array. This Skill analyzes custom hook development and useEffect usage to ensure adherence to exhaustive-deps rules and correct stale closures.

Use useMemo and useCallback when passing expensive calculations or callbacks to child components wrapped in React.memo. This Skill identifies opportunities for strategic application of these hooks to optimize re-renders and improve performance.

Optimizing a custom hook with complex dependencies requires ensuring correct dependency arrays and applying memoization. This Skill analyzes the hook to suggest precise code modifications for efficiency and correctness in complex scenarios.

Yes, combining React.memo with useCallback prevents child component re-renders by memoizing the component and stabilizing callback references. This Skill identifies these opportunities to prevent unnecessary component updates.
