React Performance Optimization Cheatsheet: Hooks, Memoization, and Lazy Loading 

import React from 'react';

const ChildComponent = React.memo(({ name }) => {
  console.log('Rendering ChildComponent');
  return <div>Hello, {name}!</div>;
});

function ParentComponent() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <ChildComponent name="John" />
      <button onClick={() => setCount(count + 1)}>Increment Count</button>
      <p>Count: {count}</p>
    </div>
  );
}
