export default function Component(){
  function handleClick() {
    alert('Clicked!');
  }
  return <div onClick={handleClick}></div>; 
}

Inline event handlers:
<button onClick={() => {
  alert('Clicked!');
}}>

Make event handlers inside components before return statement and then pass it as props, don't use parentheses or it would call it immediately.
