coffeescript-from-hell

Coffee Script is hell. Apart from https://github.com/usefulthink/coffeescript-from-hell/blob/m..., it takes the worst approach to spaces as syntax, because it doesn't enforce consistency, so with many devs you can end up with a file with two, four spaces, tabs all compiling but easily breaking. It has features their own syntax checker recommend not using, like defining objects without curly braces (which I think shouldn't even be a feature, but it was once so backwards compatibility) Coffee Script tries to be beautiful without straying too far from Javascript and it ends up being an easily broken mess. I would then recommend either typescript or purescript.
