Im a little confused about the "event.target", Versus "event.target.tagName"
Im still trying to understand the concept of event "bubbling" and "DOM traversal". I get really confused on when to use either pieces of code or how to apply it. Does "tagName" work similar to "document.elementsbyTagName"?

Assuming "event" is the parameter to an event handler (the callback function of "addEventListener"), then:
event.targetis a reference to the element that generated the event
event.target.tagNameis the "tagName" property of that element — note that tag names are UPPER CASE
document.getElementsByTagName()" is a function that you can use to find all the elements of a particular kind. Case is ignored so the argument should be lower case.
