For me, each year is worthy of a theme.
- 2018 was "as many languages as possible"
- 2019 was "Go", but only did 2 days (doing Intcode problems in 2022 for fun)- 2020 was also "Go", but got to day 12
- 2021 was "TDD (Test driven development)"
- 2022 is "Functional Programming" in Go
- Use the MU0 simulator and solve everything in ASM
- Scratch
- Typescript with Web view
