A non-blocking fold over the specified futures, with the start value of the given zero. The fold is performed on the thread where the last future is completed, the result will be the first failure of any of the futures, or any failure in the actual fold, or the result of the fold.

Transforms a JIterable[A] into a Future[JIterable[B]] using the provided Function A => Future[B].
Transforms a JIterable[A] into a Future[JIterable[B]] using the provided Function A => Future[B]. This is useful for performing a parallel map. For example, to apply a function to all items of a list in parallel.
