I saw that but the koans seemed a little too difficult. I did very much like the idea of having it done through a test framework though.

I'm doing a work-study wherein the work is done in JS, which is the issue here with teaching Ruby.

I fail to see how that fact changes anything. Ruby is literally so easy in terms of syntax, that you can teach the concepts in ruby, and "port" them back to js.
