🚀 Performance Tips

// ✅ Good - Import only what you need
import { useCounter, useDebounce } from 'react-hook-granth';

// ❌ Avoid - Imports entire library
import * as hooks from 'react-hook-granth';

// ✅ Good - Use with React.memo for expensive components
const ExpensiveComponent = React.memo(() => {
  const { count, increment } = useCounter(0);
  return {count};
});
