For example we have a page with a link that has onclick event listener on it. But handler makes stopPropagation. How I can handle that click event was made, if it's not bubble to root anymore?
e.g.
document.addEventListener('click', function(e) {console.log(e);});
a.onclick = function(e) {e.stopPropagation();};

Event.stopPropagation() The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases. It does not, however, prevent any default behaviors from occurring; for instance, clicks on links are still processed.
The event. stopPropagation() method stops the bubbling of an event to parent elements, preventing any parent event handlers from being executed.
Description: Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
DOM event propagation works in three phases: the capture phase, the target phase and the bubble phase. Roughly, the event first works its way down to the target, reaches the target and then works its way back up.
By default, event handlers are attached in the final bubble phase. If you attach a click event listener in the first capture phase, it will run before the previous handler has had the chance to call stopPropagation.
