Simple Javascript Promise Implementation (see this blog post: http://www.opensourceconnections.com/2014/02/16/a-simple-promise-implementation-in-about-20-lines-of-javascript/) ·

sample usage

var foo = function() {
var promise = Promise.create(foo)
async.wait(function() {
promise.complete();
});
return promise;
}

Doesnt work. Can you please provide a full example?

foo = new Promise(function() {return [1,2,3,4];});

foo()

TypeError: object is not a function

Also doesnt work:

foo.then(function(i) {return i}).complete()

	var Promise = function(wrappedFn, wrappedThis) {
	this.then = function(wrappedFn, wrappedThis) {
	this.next = new Promise(wrappedFn, wrappedThis);
	return this.next;
	};

	this.run = function() {
	wrappedFn.promise = this;
	wrappedFn.apply(wrappedThis);
	};

	this.complete = function() {
	if (this.next) {
	this.next.run();
	}
	};
	};

	Promise.create = function(func) {
	if (func.hasOwnProperty('promise')) {
	return func.promise;
	} else {
	return new Promise();
	}
	};
