Rx.Observable.prototype.forkJoin(second, resultSelector)

Ⓢ

Runs two observable sequences in parallel and combines their last elements.

Arguments

1. second (Observable): Second observable sequence.
2. resultSelector (Any): The default value if no such element exists. If not specified, defaults to null.

Returns

(Observable): An observable sequence that contains elements from the input sequence that satisfy the condition.

Example

var source1 = Rx.Observable.return(42);
var source2 = Rx.Observable.range(0, 3);

var source = source1.forkJoin(source2, function (s1, s2) {
    return s1 + s2;
});

var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x);
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });

// => Next: 45
// => Completed
