12 in 23 Challenge

⚠️ I just got a new job and ran out of time for this.

I raised this under Projects because I want to get fluent at a few programming languages in 2023.

Rules: Complete 5 exercises (not including "Hello World!") in 12 languages throughout the year. We'll give you a nice progress page that shows you how you're getting on, and if you complete the challenge we'll give you access to exclusive badges and SWAG. Challenge

The deadline for this project will have to keep getting bumped on the Projects page.
