e is short for event
the element on which you clicked (event.target)
https://developer.mozilla.org/en-US/docs/Web/API/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. If you want to stop those behaviors, see the preventDefault() method. It also does not prevent immediate propagation to other event-handlers. If you want to stop those, see stopImmediatePropagation().
