Hi there, James Roberts! This is how the element name is returned. This is a quote from MDN:

For DOM trees which represent HTML documents, the returned tag name is always in the canonical upper-case form. For example, tagName called on a <div> element returns "DIV".

Here is the documentation for Element.tagName

Hope this helps! :sparkles:
