// Times Promise
// By: Ryan Beltran

function times(t) {
    return new Promise(function (resolve) {
        for (var i = 0; i < t; i++) {
            resolve();
        }
    });
}

Promise.times = function (fn, t) {
    if (!t) {
        t = fn;
        fn = function () {};
    }
    var promise = times(t);

    for (var i = 0; i < t; i++) {
        promise = promise.then(fn);
    }

    return promise;
}

Promise.prototype.times = function (fn, t) {
    return this.then(function () {
        return Promise.times(fn, t);
    });
}

Example Usage:

// Logs the number 1 once, the number 2 twice, number 3 three times, and so on through 5 
Promise.resolve()
	.times( function(){console.log(1)}, 1 )
	.times( function(){console.log(2)}, 2 )
	.times( function(){console.log(3)}, 3 )
	.times( function(){console.log(4)}, 4 )
	.times( function(){console.log(5)}, 5 );
