Some Coffee Sugar for Async

Async.coffee

async = require 'async'
# Async needs some coffee script suger


###
Parallel
---------------------------------------------------
// an example using an object instead of an array
async.parallel({
    one: function(callback){
        setTimeout(function(){
            callback(null, 1);
        }, 200);
    },
    two: function(callback){
        setTimeout(function(){
            callback(null, 2);
        }, 100);
    },
},
function(err, results) {
    // results is now equals to: {one: 1, two: 2}
});

async.parallel ->
	@fn 'one': ->
		setTimeout =>
				@callback null, 1
			200
	
	@fn 'two': ->
		setTimeout =>
				@callback null, 2
			100
	
	@callback ->
		console.log @results, @err
		# @results is now equal to {one: 1, two: 2}
		# @err is null
