Review: Performance Patterns

Checklist

Re-Rendering

• No unnecessary re-renders from prop changes
• Using React Compiler when possible (reduces manual memoization)
• Context split for different concerns (avoid re-render cascades)
• Children prop pattern to prevent wrapper re-renders

Memoization

• Manual useMemo/useCallback only when needed (React Compiler handles most cases)
• React.memo used selectively for expensive components
• Dependencies correct in memoization hooks
• Not over-optimizing (premature optimization)
