Return a new iteration that will iterate over other, then over this.
Signature:
prepend<U>(other: Iterable<U> | AsyncIterable<U>): PolyAsyncIterable<T | U>;| Parameter | Type | Description |
|---|---|---|
| other | Iterable<U> | AsyncIterable<U> | Iterable to be prepended |
Returns:
PolyAsyncIterable<T | U>
a new PolyAsyncIterable that yields the elements of other and then the elements of this
The resulting iteration is of the combined generic type of this and other, allowing this method to merge the types of two distinct iterables.
