For me the real test will be maintainability going forwards. Not a JS user.

I suppose it’s one thing to rewrite code and make tests pass. But a lot of my own CPU cycles when coding go to making the code understandable, modular, editable etc. IME Claude is not great on these.

Maybe it doesn’t matter? Maybe the spaghetti makes sense to Claude, and when you say “hey add this feature”, no problem?

But maybe it will turn into a worse ball of spaghetti, with no nicely curated tests, hacks on hacks on hacks and never ending loops of whackamole of “just change this one line and rerun tests”.

I can imagine both - let’s see.
