In what course or video is .map() initially covered?

I've been taking the Treehouse Front End Web Development track have only just heard of .map(). With that, Guil just mentions using it and doesn't go into detail about it. I'm wondering in what course or video this method was originally covered?

I think this video has a reasonable good explanation of maps https://teamtreehouse.com/library/transform-array-items-with-map

Hope you find it useful
