Why we preferred event-delegation model over earlier event-inheritance model?

Answer 1

The event-delegation model has two advantages over the event-inheritance model.

1. Event-delegation helps in event handling by objects other than those who generate the events.
2. Help in differentiating between component design and its use.
3. Event-delegation performs much better in applications where generation of events takes place.
4. Event-delegation model does not repeatedly process unhandled events, which cause improvement in the performance.
