learn-you-a-haskell VS learn4haskell

you start that way, but don't do http://learnyouahaskell.com really?

Elm is a statically typed language inspired by Haskell. The natural step would be to use Elm on the frontend and Haskell on the backend. And that's what I tried to do. I read with some difficulty the Learn You a Haskell for Great Good! book (available for free here) and learned a lot of cool stuff. But creating a complete backend using Haskell proved to be more than I could chew. So I decided to look for alternatives...

Here y’go!

Definitely check out: http://learnyouahaskell.com

You see? It's not simple but you'll get there if you persist. Most Haskell and Purescript books cover it. Personally it clicked for me going through the "learn you a haskell" book. http://learnyouahaskell.com

You just wait until you start reading this http://learnyouahaskell.com/

This is my second time learning Haskell. I’ve learned it at the university in a course and through http://learnyouahaskell.com, but I’ve mostly forgotten everything but the basics.

If reading books isn’t exactly your thing, here are some Haskell courses that should get you writing Haskell as fast as possible. There are two options to choose from here: something like Type Classes or learn4haskell can be very useful for getting started with the Haskell syntax and basic language constructs, while the more university-focused courses from Erik Meijer or Graham Hutton will help you start thinking like a functional programmer.

If you are already advanced in other programming languages, this course will get your feet wet: https://github.com/kowainik/learn4haskell

Learn4Haskell - Great for getting your feet wet with Haskell's syntax, and the fundamental typeclasses. They teach the concepts, and give you exercises on Haskell files which I find really neat. Akin to vim tutor. You can also run test cases which I found helpful.

You can check Learn4Haskell. It contains dev env setup instructions, explanations of topics with exercises. And the bonus feature is that course authors will review your solutions and provide feedback.

Later, I found repos like kowainik/learn4haskell where we can create 4 valid PR's and learn some Haskell along the way. As of now, I have raised 2 PR's to this repo and I must say learning Haskell and functional programming concepts has been fun.

Most project maintainers are very much interested to help beginners get into open source, so you just have to get started. Just have a look at one of my PR.
