/**
* Collects all source emissions and emits them as an array when the source completes.
*
* <span class="informal">Get all values inside an array when the source completes</span>
*
* 
*
* `toArray` will wait until the source Observable completes before emitting
* the array containing all emissions. When the source Observable errors no
* array will be emitted.
*
* ## Example
* ```ts
* import { interval } from 'rxjs';
* import { toArray, take } from 'rxjs/operators';
*
* const source = interval(1000);
* const example = source.pipe(
* take(10),
* toArray()
* );
*
* const subscribe = example.subscribe(val => console.log(val));
*
* // output: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
*
* ```
* @return An array from an observable sequence.
* @method toArray
* @owner Observable
