### `Rx.Observable.prototype.zipIterable(...args, [resultSelector])`
[Ⓢ](https://github.com/Reactive-Extensions/RxJS/blob/master/src/core/linq/observable/zipiterable.js "View in source")
Merges the current observable sequence with iterables such as `Map`, `Array`, `Set` into one observable sequence by using the selector function whenever all of the observable sequences or an array have produced an element at a corresponding index.
#### Arguments
1. `args` *(`Arguments`)*: Arguments of Arrays, Maps, Sets or other iterables.
2. `[resultSelector]` *(Function)*: A function which takes the inputs at the specified index and combines them together. If omitted, a list with the elements of the observable sequences at corresponding indexes will be yielded.
#### Returns
*(`Observable`)*: An observable sequence containing the result of combining elements of the sources using the specified result selector function. If omitted, a list with the elements of the observable sequences at corresponding indexes will be yielded.
#### Example
```js
var array = [3, 4, 5];
var source = Rx.Observable.range(0, 3)
.zipIterable(
array,
function (s1, s2) { return s1 + ':' + s2; }
);
var subscription = source.subscribe(
function (x) {
console.log('Next: %s', x);
},
function (err) {
console.log('Error: %s', err);
},
function () {
console.log('Completed');
});
// => Next: 0:3
// => Next: 1:4
// => Next: 2:5
// => Completed
```
