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
