## March 15, 2024 - What I Learned Today

- Learned about React's useCallback hook and how it prevents unnecessary re-renders
- Discovered that it's only useful when passing callbacks to optimized child components
- Realized I was overusing it in my previous projects without understanding the performance implications

## This Week's Challenge

- Problem: My React app was re-rendering too often causing performance issues
- Approach: Used React DevTools Profiler to identify components that render unnecessarily
- Outcome: Found 3 components that were re-rendering due to object creation in render, fixed with useMemo

## Monthly Insight

The key to React performance isn't using every optimization hook available—it's understanding when and why to use them. Measure first, optimize second.
