Why I hate Coffeescript.

gistfile1.txt

a = undefined   # var a;
a = "lol"       # a = 'lol';
rawr = (->      # rawr = function() {
  a = "wat"     #   var a = 'wat';
  a             #   return a;
).call()        # }.call();
console.log a   # console.log(a);
# returns 'wat' # returns 'lol'
# What the fucking fuck, Coffeescript...

@ajmurmann, it's showing that coffeescript doesn't use var within function definitions. They don't like var.

(function() {
  var a, rawr;

  a = void 0;

  a = "lol";

  rawr = (function() {
    a = "wat";
    return a;
  }).call();

  console.log(a);

}).call(this);

var a, rawr;

console.log(a);
