esid: sec-array.prototype.entries
description: >
New items in the array are accessible via iteration until iterator is "done".
info: |
The method should return a valid iterator with the context as the
IteratedObject. When an item is added to the array after the iterator is
created but before the iterator is "done" (as defined by 22.1.5.2.1) the
new item should be accessible via iteration.
