Iiiiinteresting. Definitely agree that the first half of the article isn't exactly data structures yet. But I just struggle with calling something "An inroduction to X." Have you ever heard "an introduction" and thought "oh, that's what I need!" I picture a super-dry textbook. Or one of those YouTube videos that promises to teach you how to do a thing but starts off with the person saying, "Now, before we get started..." and talks about nothing for 5 minutes before actually teaching you the thing.
