In my experience when learning functional programming with Haskell there are two kinds of complexity: 1. Complexity caused by the change of paradigm: This specifically hits programmers with a lot of experience in OOP languages. For getting into the FP-mindset your brain needs a bit of time to get rewired. You need to switch thinking about mutating objects to thinking in mapping streams of data. Given that many OOP languages are adopting functional ideas like map and fold/reduce, nowadays a lot of developers already have a bit of experience in thinking in the FP-way, and this will get better with time. 2. Complexity caused by the tools: There's a reason the author in the above post started out with Elm instead of Haskell :-) Writing a few recursive functions in haskell is still pretty simple. Where it get's very complex is when you want to build real world applications. To build a simple web app you need to 10s of decision on what tools and libraries to use. Here's a couple questions you'll need to find an answer to when building a haskell app: - What GHC and what language extensions do I need? How do I install it? - What package manager do I use? Cabal, nix, stack? - What web server library? - What database library do I need? Do I need an ORM, are there even ORMs in haskell even though there are no objects? - What HTML template library to use? - How do I compose it all together? What is a monad stack? When you have only very few experience in haskell it's really hard to not get stuck here. The quality of documentation of most haskell tools also doesn't very much help here. I believe that the value haskell can bring is signifcant, and by fixing the tooling situation we can a lot more people to adopt haskell in the future. With IHP we're trying to fix the tooling situation and build a haskell-based web framework that is as easy to use a rails or laravel :) To combine the benefits of purely-functional programming with the RAD approach of rails, laravel and django. It's now already the most active haskell web framework and we have many people starting their haskell journey with IHP. We have live reloading in dev mode, a JSX-inspired template language and many code generators to quickly get started with shipping real world apps.
