Iterables are JavaScript objects that can be iterated over or looped through using the popular for-of loop. This video will get you up to speed with the powerful iterator object.

Understanding iterables and iterators will allow you to have a stronger understanding of the JavaScript language and give you more freedom of how you construct complex data structures.

Hi Ijemma, out of curiosity what are you using to debug in your console like this?

at 3:26 when you clear the screen it makes it hard for me to understand as the following bits are relying on the part you just cleared. I would have liked to have seen the entire content without having the console cleared. I had to go back and go forward a few times to sort it out - where as I could have pressed pause and seen the whole sequence if it had not been cleared. One other thing - the custom iterator was just adding 1 to the prior number with ++, if I understand correctly you could have done something more interesting here? like add +2 or *2? that would have made for a more interesting example as ++ just seemed too natural. Nice job though, I enjoy your videos!

I like your way you teach by giving simple examples then go to difficult example. Is it also possible to speak a little slower?
