What does getElementsByTagName do?
I understand getElementsById but just wanted a quick idea of what getElementsByTagName means and does?
Does it select all elements on the page with the same tag/element name?

Yup, it returns a collection of all elements in the document with that specified tag name, as an HTMLCollection (array like list of html elements) object.
So if you wanted the
body element of the document you could use
Since there is only 1 body tag on the document the node list has a length of 1 or index 0.
