Re: [Haskell-cafe] off-topic question: why invent new Haskell-like compile-to-js functional languages when we have awesome js_of_ocaml ?

That's great news. I wonder if that means it'll be end for Fay and similar languages?

GHCJS's Hello World is 2.1M worth of javascript (well, that's how it was several month ago, maybe it's better now?). And even google closure compiled with advanced optimizations it's ~500K.

Fay's output is 5K after google-closure-mumbo-jumbo.

I'm aware of this, but when I first tried it a few months ago, it was not easy to use at all. Is it changed now?

Last I heard, Luite was waiting for GHC 7.8 to be released because it contains changes that will allow him to upload ghcjs to hackage and then you will be able to just cabal install it. I could be wrong though.

As far as I know, that's correct.

The easiest way to install and use it right now is using their Vagrant setup:
