A async function that I wrote as everything else seemed too complex for what I needed

async.js

function async (fun, args) {
    if(!fun.length) return;
    args = args || [];
    var call=fun.shift();
    if(typeof call == "function") call = [ call ];
    var count=call.length;
    var n=0;
    var ret=[];
    while(call.length) {
	call.shift().apply((function (num){ 
	    function r (a) {
		ret[num]=a;
		if(!--count)
		    async(fun, ret);
	    }
	    for(var c=0;c<args.length;c++)
		r[c]=args[c];
	    return r;
	})(n++));
    }
}

exports.async = async;

example.js

var async = require('./async');

async([
 [
  function () {
   // do something
   this("result");
  },
  function () {
   // do something
   this("result2");
  }
 ],
 function () {
  // this[0] == "result" && this[1] == "result2"
 }
]);

Did you see https://github.com/creationix/step ?

I have not seen that before, and it is similar, but this was a decently quick hack that I used for jsapp.us

Looked similar in syntax ^_^
