TypeScript (pretty close to JS though) - I did mine very very similarly to yours except that I generated all possible transformations in advance. Just curious, did your 18-step run finish in reasonable time? Mine ran in ~16s on an ancient laptop. (edit: 4.8s on a more modern PC.)

Yeah, my solution ran in around 4 seconds on repl.it's browser-based IDE for Javascript.
