Advent of Code 2021 has come to an end.
I decided to go with TypeScript on Deno, the same approach as last year, which I think works great for these kinds of puzzles. I didn't manage to finish all puzzles though. I went off on a vacation in December skiing and I didn't have the time to catch up afterward.
However, if you are interested to look at the effort, feel free to have a look at my repo below.
