Now that we have introduced the for...of loop and symbols, we can comfortably talk about iterators.
It is worth for you to learn about iterators, especially if you like lazy evaluation, or you want to be able to describe infinite sequences. Understanding of iterators also helps you understand generators, promises, sets, and maps better.
Once we cover the fundamentals of iterators, we will ...
