How do I return an array from Rxjs subscribe method?

Question

I have this code:

Rx.Observable.from([1,2,3,4,5,6])
.subscribe(x=>console.log(x));

How can I return an array from subscribe instead of the subscribe iterating through the array elements from the .from() method?

I want the x argument to be an array and to console.log() this array.

Observable.of([...])? .from emits each thing in the iterable as a separate element of the stream. — jonrsharpe

ReactiveX has the "to" operator, which can be used with RxJS as toArray:

Rx.Observable.from([1,2,3,4,5,6])
    .toArray()
    .subscribe(x=>console.log(x));

Or, pass it like this:

Rx.Observable.from([[1,2,3,4,5,6]]);

an array whose first element is an array.
