What is “propagation”?

Propagation refers to how events travel through the Document Object Model (DOM) tree. The DOM tree is the structure which contains parent/child/sibling elements in relation to each other. You can think of propagation as electricity running through a wire, until it reaches its destination. The event needs to pass through every node on the DOM until it reaches the end, or if it is forcibly stopped.

Event.stopPropagation()

These two methods are used for solving the previously mentioned problem regarding event propagation. Calling Event.stopPropagation() will prevent further propagation through the DOM tree, and only run the event handler from which it was called.
