Coding puzzles running from December 1-25. See adventofcode.com.
This was my first year participating, though I revisited some 2020 puzzles as a warmup. Decided to do go rather than my original plan of python and then go so it'll hopefully be a better learning experience in a language I'm less familiar with.
Optimistically this should be a bit easier, but I could use some good reps on my TS skills for future projects.
