So adventofcode.com Advent of Code starts today / tomorrow what language is everyone using this year?

For my next software project I'll use the SOCKS stack.
That is, I'll pick software for which I got socks at a conference.
So far I've got Laravel, Turso and @circleci.bsky.social
Kinda like where this is going!
