From [1]:

    A generic iterator function, which can be used to seamlessly
    iterate over both objects and arrays.  Arrays and array-like
    objects with a length property (such as a function's arguments
    object) are iterated by numeric index, from 0 to length-1.  Other
    objects are iterated via their named properties.
