how would you answer this?

How would you select the body element using document.getElementsByTagName, and store it in the variable body?

(Hint: Don't forget that this method returns a collection, not a single element.)

const body =

It looks like they have basically given you the answer. If you are not understanding it, you may need to rewatch the videos, or look in the Teachers Notes, they probably have a link to the DOM reference at MDN.

This part may give you more clues : https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementsByTagName

I don't understand what you're getting at. Why not just select it with document.querySelector? Though I get that you're trying to ask a tricky question, there would literally be 0 use cases for using getElementsByTagName to select the body, so therefore, I think this question is pointless and doesn't really merit any deeper thought.

Tucker : I think you are missing the entire point. This is a quiz question, not Michael's own.

Michael : It looks like this was covered previously on the forums : https://teamtreehouse.com/community/how-do-you-select-the-htmls-body-using-documentgetelementsbytagname

Ohhhh. lol my bad. I wasn't actually working through this course I just got an email from Treehouse inviting me to answer random questions. I should have looked into it a bit more before answering. My apologies, Michael.
