Multiple template fetching with promises

gistfile1.js

var getTemplate = function(url){
	var deferred = $.Deferred();
	// simulate latency
	setTimeout(function(){
		deferred.resolve('template-result-done-'+url);
	}, 1000);
	return deferred.promise();

var fetch = function(/* params string[] urls */){
	var length = arguments.length;

	if(length){	
		var i = 0;
		var promises = [];
		while(i < length){
			promises.push(getTemplate(arguments[i]))
			i++;
