I personally prefer Haskell's syntax. I find myself using JavaScript transpilers like BuckleScript to take me into a typesafe land with ML syntax rather than using a language like TypeScript with Java like syntax.

That said, I really appreciate seeing work like this. Haskell is super powerful and it's great to see transpilers like this that are lowering the bar of entry to Haskell to those more familiar with the traditional languages. Nice job!
