I've never done AoC but I've done other programming-related challenges before. I come from a non-IT background (mech eng), and I'm currently away for work for the first several days with only their locked-down laptop.
Normally I'd break out Python for this, but given the constraints maybe I should try to see how far I can get through this in Excel. It'd be a fun little challenge :)
My approach here would be to make an index.html file with a script tag and drag it onto whatever browser is available. Then again I have made peace with JavaScript!
(I think you could even use typescript with this method with the on the fly babel transpiler (you just include a script tag) but I haven't tried that.)
Interesting, the in-browser one doesn't do type checking? They're actually adding that to JS itself as far as I can tell -- the ability to strip TS types and run it as-is.
