Many people don't realize what a truly awesome language JavaScript actually is. Unfortunately all current implementations kind of suck.

The problem with JavaScript is that it most implementations are nowhere near as efficient as they could be (even V8), at least for the kind of programming I want to do. I really like functional programming. You can write super 

Also on the horizon, some people want to make it more like ML!  

Do you know ML or any of it's offshoots: Standard ML, OCaML or F#? At its core I think it is safe to say that Scala also is essentially ML. It is kind of a kissing cousin of OCaML.

I am really unhappy about the effort to make JavaScript more like ML, where there are multiple kinds of variable declarations (e.g. "var" and "let") and ease of use takes a back seat
