A JavaScript Iterator allows you to move through a collection in a one-at-a-time fashion. In this tutorial we will look at how to set up and use an iterator.

Seems powerful. I've been confused by symbols for quite some time now, so it was nice to see an example.

Great video, as usual ! Youtube needs more tut creators like you :)

Quick tip: hitting the up arrow in console will run your last typed instruction :P

I haven't used the iterator but I have used function* for generators. They both have the concept of retrieving a next value.

Can see this being especially useful in e-commerce type apps where you can control the bandwidth required and number of results produced. 10000 products? Just show the first 100 and pull the next batch as the user clicks next.

You know, this would have been a nice feature if it was possble to go in reverse trough the iterator like you can with iterators in Java. I don't see much use of it without that function

Very clear explanation, however are there any videos about creating custom iterators for the objects (which aren't iterable)?
With best regards,

There is some code I borrowed from stackoverflow which I modified into a generator.
This code yields all possible permutations of the array one by one.

JavaScript doesn't have a hasNext() on it? That's a bit disappointing.
