Racket has a ton of different types of for loops for iterating over data structures etc. and collecting the results (or ignoring them). They're implemented under the hood using recursion but that's hidden from the user and it should be trivial to go from then to other languages. Maybe this class they're talking about didn't cover them? https://docs.racket-lang.org/guide/for.html https://docs.racket-lang.org/guide/for.html
