...Coffeescript was designed specifically to compile 1:1 to matching js

possibly initially, but there's a lot of constructs in coffeescript that aren't in js eg existential operator

    solipsism = true if mind? and not world?

compiles to

    var solipsism;
    if ((typeof mind !== "undefined" && mind !== null) && !(typeof world !== "undefined" && world !== null)) {
      solipsism = true;
    }

see also splats http://jashkenas.github.com/coffee-script/#splats, function binding and comprehensions over collections eg

    eat food for food in ['toast', 'cheese', 'wine']
