const app = document.getElementById('app');
app.innerHTML = `
  <h1>JavaScript DOM</h1>
  <div class="one">
    <div class="two">
      <button type="button" class="three">
        Click Me
      </button>
    </div>
  </div>
`;
 
const one = document.querySelector('.one');
const two = document.querySelector('.two');
const three = document.querySelector('.three');
 
function handleClick(event) {
  event.stopPropagation();
  // event.stopImmediatePropagation();
  console.log(event.target);
}
 
one.addEventListener('click', handleClick);
two.addEventListener('click', handleClick);
three.addEventListener('click', handleClick);
 
three.addEventListener('click', event => console.log(event), { capture: true });

  

When use 'stopPropagation', the code:

three.addEventListener('click', event => console.log(event), { capture: true });

will still running.

 

But when use 'stopImmediatePropagtion', that line of code will not run any more
