Pros and Cons of using e.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 propagation to other event-handlers of the current element. If you want to stop those, see stopImmediatePropagation().
