Functional Sets Course

Hey there! I’ve just put the finishing touches on and published a new course based on some blog posts I wrote over the last year.

In it, you’ll learn how to replicate the Set API. If you’re interested in how to create your own data structures in Elm, you’ll probably be pretty interested!

(p.s. this is the first set of posts I’ve turned into guides, which I’m going to be keeping up-to-date for Elm 0.19 and beyond.)


I have not seen this before now.
This was very well written.
I learned a lot reading through this. Not just about sets, but also how map/filter/fold++ works in general. :+1:
