Hey all! I thought I’d start a thread for folks who, like me, are working through Advent of Code 2025 in Mojo. Feel free to share questions, solutions, and reflections here or in the discord channel. Looking forward to seeing how folks approach this year’s challenges.

I want to circle back to 2024 Mojo at some point. A lot of development in the ecosystem since then. It seems so long ago to me
I’ve been posting daily solutions over on Discord, but they are all found here! sstadick/aoc-2025: Advent of Code 2025 - Codeberg.org
