    • Item

    • MappedItem

    Parameters

    • mapper: Unary<Item, MappedItem>

      Mapper function.

    Returns (<Iterable>(iterable: Iterable) => Iterable extends AsyncIterable<Item> ? AsyncIterableIterator<MappedItem> : IterableIterator<MappedItem>)

      • <Iterable>(iterable: Iterable): Iterable extends AsyncIterable<Item> ? AsyncIterableIterator<MappedItem> : IterableIterator<MappedItem>

      • Type Parameters

        • Iterable extends AsynchronousIterable<Item>

        Parameters

        • iterable: Iterable

        Returns Iterable extends AsyncIterable<Item> ? AsyncIterableIterator<MappedItem> : IterableIterator<MappedItem>
