{{alias}}( src[, mapFcn[, thisArg]] )
    Returns an iterator which iterates from right to left over the elements of
    an array-like object.

    When invoked, an input function is provided three arguments:

    - value: iterated value
    - index: iterated value index
    - src: source array-like object

    If an environment supports Symbol.iterator, the returned iterator is
    iterable.

    If an environment supports Symbol.iterator, the function explicitly does not
    invoke an array's `@@iterator` method, regardless of whether this method is
    defined. To convert an array to an implementation defined iterator, invoke
    this method directly.

    Parameters
    ----------
    src: ArrayLikeObject
        Array-like object from which to create the iterator.

    mapFcn: Function (optional)
        Function to invoke for each iterated value.

    thisArg: any (optional)
        Execution context.

    Returns
    -------
    iterator: Object
        Iterator.

    iterator.next(): Function
        Returns an iterator protocol-compliant object containing the next
        iterated value (if one exists) and a boolean flag indicating whether the
        iterator is finished.

    iterator.return( [value] ): Function
        Finishes an iterator and returns a provided value.

    Examples
    --------
    > var it = {{alias}}( [ 1, 2, 3, 4 ] );
    > var v = it.next().value
    4
    > v = it.next().value
    3
