I’ve put together a list of blog, guides, articles, videos and courses I found useful by actually reading them, trying them, watching them, completing them. I’ve gone over a lot of stuff on the internet and these few items deserve a mention and are well worth your time.
The Learn you a Haskell for Great Good! book is a great way to learn functional programming concepts. It explains things like currying, type constructors, kinds, monoids, functors, applicative functors, monads in a very clear, easy-to-follow style. Yes, I know, it’s not Scala. It’s Haskell. And yes, you should learn you a Haskell. For great good it will do you.
