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.

That was so handy! I will be using these in practice today. Thanks!

Nice explanation! iterators could be very useful in recursion!

Nicely explained..can you make a video on symbol?

good ...

[@bmehder]

Don't forget about recursion. 🙂

Nice

[@paulward5452]

yes, very good

[@bazy1983]

Which one of these methods is synchronous ? Thanks for this video

[@AllThingsJavaScript]

They are all synchronous in returning the results. You could make an argument that the iterator is asynchronous because you can make it non-blocking.
