I just noticed that Roc has a tutorial now!
The last time I poked at it, it was difficult to find any documentation. Now there's a pretty neat onborading guide.
I'm excited for Roc. I enjoy the aesthetics of the language, and totally trust Richard Feldman's design sensibility. Let's hope this goes places.
Also: this might be a good language for Advent of Code 2023.
Also this comparison to Elm is nice: https://github.com/roc-lang/roc/blob/main/roc-for-elm-programmers.md
