Ask HN: What's the best material to learn Racket?

One of the best resources I've found is Programming Languages: Application and Interpretation by Shriram Krishnamurthi[1]. It walks you through building a small interpreter and language in Racket. Not only does it teach Racket, but it helps understand how and why the language works.

How to Design Programs, Second Edition[1] is a good resource for learning how to model and program in a style that will translate well to full-blown Racket. See also Realm of Racket[2].

The Racket Cheat Sheet[3] is handy, and provides some useful links at the top (cf. "Sites", "Community").

I took this course the first time Kiczales taught it online. That was on Coursera's platform in 2013.

It would be my suggestion.

Does anyone use Racket in the wild? For real projects, not counting the Racket team.

The software running HN is written in the Arc language [1], whose interpreter is written in Racket.
