React useMemo | Mastering of React | Part - 20

Summary
Memoizing Functions in React with `useMemo`
Highlights
- 🔧 `useMemo` enhances performance by conditionally re-rendering components based on specified dependencies.
- 🎯 `useMemo` isolates specific logic within a component, allowing for efficient updates.
- ⚖️ `useMemo` improves performance by preventing unnecessary re-renders when dependencies remain unchanged.
- 💡 `useMemo` takes a callback function and dependency array, only re-evaluating if dependencies change.
- 📚 In React 19, `useMemo` may become redundant as functions are memoized by default.
