The most Haskell-like and popular are:

- http://www.purescript.org/

- https://github.com/faylang/fay

- https://github.com/ghcjs/ghcjs

- http://elm-lang.org/

Each has it's own focus and strengths and weaknesses.

There is a long page on the Haskell wiki on the subject: https://www.haskell.org/haskellwiki/The_JavaScript_Problem

Michael Snoyman gave a really good talk recently which covers GHCJS and Fay: https://www.youtube.com/watch?v=XfINRj5OzGw

PureScript has the advantage that it has a very lightweight runtime and maps to JS quite well.
