React wraps native events inside SyntheticEvent, ensuring consistent behavior across browsers.

function ButtonClick() {
  const handleClick = (e) => {
    alert('Button clicked!');
  };

  return <button onClick={handleClick}>Click me</button>;
}

✅ Use camelCase event names (e.g., onClick, onChange).

✅ Don’t call the handler directly (onClick={handleClick()} is wrong).
