I would like to humbly second this notion. Especially since you can autogenerate Elm decoders based on Haskell types to reduce boilerplate and duplication between frontend and backend, while mostly retaining a strong sense of type safety. You can also use Elm as an introduction language to new developers, without all of the complexity of haskell’s higher order abstractions, and then introduce them to haskell when they’re comfortable with elm. (I did this with Servant as a backend, but IHP is wonderful as well!)
