Question:What is the advantage of the event-delegation model over the earlier eventinheritancemodel?
Answer: The event-delegation model has two advantages over the event-inheritance model. First,it enables event handling to be handled by objects other than the ones that generate the events (or their containers). This allows a clean separation between a component's designand its use. The other advantage of the event-delegation model is that it performs muchbetter in applications where many events are generated. This performance improvementis due to the fact that the event-delegation model does not have to repeatedly processunhandled events, as is the case of the event-inheritance model.
