Event delegation

DOM events bubble up through the DOM tree and register against every element up to the top. The object passed to the listener (call it e for example) will have the e.target property, which was the element that was interacted with directly ("clicked", etc.) and the e.currentTarget property, which is the element that was listening when this event listener caught the event.

e.stopPropagation() will keep the event from continuing to bubble up the DOM tree.
