Understanding how events propagate is an important factor in being able to leverage Event Delegation. Any time one of our anchor tags is clicked, a click event is fired for that anchor, and then bubbles up the DOM tree, triggering each of its parent click event handlers:
<a>
<li>
<ul #list>
<div #container>
<body>
<html>
document root
This means that anytime you click one of our bound anchor tags, you are effectively clicking the entire document body! This is called event bubbling or event propagation.

Hi you
Event bubbling causes all events in the child nodes to be automatically passed to its parent nodes. The benefit of this method is speed because the code only needs to traverse the DOM tree once.

Occasion effervescent guides a meeting to its intended target, it works like this: A key is visited and the case is forwarded to the key. If a meeting owner is set for that item, the case is activated. If no event owner is set for that item, the case pockets up (like a percolate in water) to the objects parent.
