Javascript Question

Is there a fully functional paradigm language that transpiles to JavaScript?

Is there a language which transpiles to JavaScript (like TypeScript, CoffeScript etc.) and is almost purely functional (like Haskell, Erlang, F#)?

I know there are libraries which helps maintain immutability (Underscore), and there are a lot of cool array functions and lambdas in ES6. But what I'm looking for is a functional like syntax and transpiler for it, so I can write functional JavaScript with not much effort.

In Elm and PureScript functions are curried by default. In Scala Currying can be done very easily by using multiple parameter lists:

def curried(param1: Int)(param2: Int): Int = ...
