RxJS equivalent of async.parallel

RxZipper.js

var Rx = require('rx');

var zipper = function () {
    // Turning arguments from an object into an actual array so we can use things like map()
    return Array.prototype.slice.call(arguments);
};

var array; // Given some array of Observables that you want zipped together

// Or the more classical case where given an array of data to operate on, simply map them into observables
var data = [0, 1, 2, 3, 4, 5];
array = data.map(function (element) {
    return Rx.Observable.create(function (observer) {
        observer.onNext(element);
    });
});

// After transforming
Rx.Observable.zip.apply(Rx.Observable, array.concat(zipper)).subscribe(function (zipped) {
    // Yay! Zipped data!
    console.log(zipped);
});

@alanmquach You may now simply use zipArray
