I am not understanding the difference between event delegation and propagation

i understand the idea of delegation, its more so the action of attaching an event listener to a parent node to activate the NEW child node

but the definition of propagation is totally throwing me off, i feel like im reading the same definition twice sometimes

Propagation is the aspect of events that causes them to passed up through the ancestor elements. It's also called "bubbling", and it's the reason that delegation works.

For more details, see the MDN Introduction to events page.
