Rx.Observable.prototype.zipIterable(...args, [resultSelector])

Ⓢ

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

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
