I don't understand what exactly the event.target.tagName piece of code is doing. My program is running fine, I just want to know exactly this is doing. Thanks for any clarification you can give!

The "event.target" is the element that was clicked, and testing the TagName for equality with "BUTTON" insures that the code in the conditional block only runs if the element that was clicked is one of the buttons.

14,768 PointsThanks for clearing that up! In this situation, why do we need to but "BUTTON" in all CAPS?
