Useful and clear, thanks. I often add named properties to array objects and stick to for-next loops to iterate by numeric index as care is needed if using array methods. For example, for-in will include named keys as well as numbered indices, while the 'of' method will include named object keys as undefined. Iterators will not be done until the numbered indices AND named properties are iterated (but will give undefined values for the named properties). You can't go wrong with for-next loops.
