There are some ways in which Haskell's type system actually makes it significantly better at Elm's core job than Elm itself.

Type classes could certainly be argued to be one of those things, but also just existential types makes "reducers" a lot more pleasant to work with.

Check out e.g. Edward Kmett's library or read e.g. Gabriel Gonzales' post on folds if you want to know more.

Yeah, but I’d love to see the average JavaScript developer get up and running with Haskell in just two weeks.
