cancelable Event Property
Description

if an event is cancelable.
Otherwise it returnsfalse.
The cancelable event property is read-only.
An event is cancelable if it is possible to prevent its default action.
Event Bubbling
Event bubbling directs an event to its target. It works like this:
| When an element (like a button) is clicked, an event is directed to the element. |
| If an event handler is set for the element, the event handler is triggered. |
| Then the event "bubbles up" to the elements parent. |
| If an event handler is set for the parent, this event handler is triggered. |
| The event continues to bubble, until it reaches the top (the document element). |
Prevent Bubbling:
The stopPropagation() Method stops bubbling.
Prevent Default Action:
The preventDefault() Method cancels an event (the default action will not occur).
