Section Intro

In this section we're going to cover a few things related to concepts that are a little more advanced and not as common. We're going to talk about iterators, which are objects that defines a sequence of values. Generators, which are used to create iterators and then we're going to move to data structures including sets and maps, which are built-in to JavaScript, but we're also going to create some data structures that are well known in computer science, but not built in to JavaScript. This includes stacks, queues and linked lists. What we'll do is create some classes that allow us to instantiate an object and give it methods to behave like these data structures. So this stuff is a bit more advanced, but I think you'll learn a lot as we go. So let's get into it.
