These are my solutions to the haskellbook. Mostly, the solutions were put in src/ChXX.hs. Some of the solutions per chapter were split up so I didn't have overlapping implementations.
The projects in the book which are separate applications all have their own subfolders, such as hangman or morse.
I don't have solutions for anything before Chapter 9, mostly because I already knew a bit of Haskell coming into this and those chapters were very easy.
I hope these solutions are of use to someone, feel free to PR if you come across any errors.
I've used this repo for some additional Haskell learning.
typelevel has some basic type level programming with functional dependencies, type families, GADTS, etc.
go-haskell are the exercises from A Tour of Go in Haskell which was a interesting little book of Go-like idioms in Haskell.
