The bubbles event property is used for returning a Boolean value which indicates whether an event is a bubbling event or not. The event is triggered if an event handler is set for that object, if not so then the event bubble up to the object’s parent. The event bubble up until it reaches the document object or handled.
What is event bubbling? Consider a situation an element is present inside another element and both of them handle an event. When an event occurs, in bubbling, the innermost element handles the event first, then outer, and so on. Please refer this for details.
Return Value: The bubbles event property returns true if the event can bubble up through the DOM, else it returns false.
