Front End Web Development Techdegree Student 15,570 PointsIm 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"?

-
event.target
is a reference to the element that generated the event -
event.target.tagName
is 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.
