What is the most production-level Haskell to JavaScript compiler, to write code running in the browser? [closed]

Answer 1

You may find this List useful: https://github.com/jashkenas/coffee-script/wiki/List-of-languages-that-compile-to-JS

From the List:

* UHC (Utrecht Haskell Compiler) backend converts UHC core to JavaScript, allowing the compiling of Haskell code to JS.
* YHC (York Haskell Compiler) backend, as above but with YHC core language.
* jshaskell

I know its not Haskell but Coffee script is expression based and rather elegant IMHO.
