Expert

Verified

Event-delegation model consist of two benefits over event-inheritance model.

a) Event delegation model allows event handling by objects other than ones which produce the events. This permits a clean separation between the component's design and its use.

b) This performs much better in applications where numerous events are produced. This performance enhancement is due to the event-delegation model doesn’t have to be repeatedly process unhandled events as is the case of event-inheritance.
