Exercism is an amazing platform, basically providing free education on many programming languages! I highly recommend you check it out no matter what. Oh and did I mention it is free?
Exercism has a new annual challenge for 2024. This year we're focussing on digging deeper into the languages you use day-to-day rather than trying new languages.
Each week we'll be launching a different programming challenge, with videos exploring different approaches, looking at some of the best solutions from the community, and highlighting some of the more wild and ridiculous solutions too.
It's totally free (Exercism is a free, open-source, not-for-profit organisation for programming education)
