JS yield - what is it and what do it ?

Question

I will appreciate a good explanation about it...

Answer 1

Okay, so the * makes the function a generator function: it returns an iterator, which is an object, that has a value, done value and a next method.
yield stops the function "execution", and returns the value after it.
Giving an argument to the next method will replace the yield statement with that value. So, y will be 7.
