I disagree with GP, it’s much more like Haskell than JavaScript. Function application is whitespace, functions can only have one argument, everything is an expression, let blocks are the way you define and scope variables. I see very little relation to JavaScript at all, to be honest.

You've listed syntactic sugar, not anything about the actual language.

I don't see any sense where syntactic sugar is not part of the language. I don't really care about how it works behind the scenes, the syntax is the part that I touch as a programmer.
