If we're speaking of competition and JavaScript, then a much stronger competitor would be PureScript. http://www.purescript.org/ http://www.purescript.org/ PureScript is a Haskell dialect that was built specifically to run on top of JavaScript engines. Specifically, compared with Haskell, it is strictly evaluated (whereas Haskell is non-strict / lazy, well almost). However it eliminates some of Haskell's baggage, but retains Haskell's functional purity. It's all around an awesome programming language for FP that targets JavaScript engines, far surpassing any other attempt.
