The #48in24 Challenge
exercism.org
Try out a new programming challenge each week. Broaden your horizons and level up your programming skills as your explore the varied paradigms and ideas that different languages embrace. It's free, fun, and useful!

Just because Exercism doesn’t offer your favorite language as an official track, it doesn’t mean we can’t play at all. Post some solutions to the weekly challenges in the language of your choice!
