Capturing and Bubbling

You have used the familiar addEventListener apparatus. It has two arguments, the first is an event type such as click or mousemove. The second is a function that is called when that event occurs.

There is a third, opional arguement known as useCapture, which we will look at today.

When an element detects an event, that event propagates through the parent events all the way to body, html, and document.

This upward propagation is called bubbling. Once this occurs, the process reverses in a stage known as capturing.
