 It's indeed very simple. We add the `async` keyword, and the generator now can use `await` inside of it, rely on promises and other async functions.
 
-Technically, another the difference of an async generator is that its `generator.next()` method is now asynchronous also, it returns promises.

 In a regular generator we'd use `result = generator.next()` to get values. In an async generator, we should add `await`, like this:

 So far we've seen simple examples, to gain basic understanding. Now let's review a real-life use case.
 
-There are many online services that deliver paginated data. For instance, when we need a list of users, a request returns a pre-defined count (e.g. 100 users) - "one page", and provides an URL to the next page.

 The pattern is very common, it's not about users, but just about anything. For instance, GitHub allows to retrieve commits in the same, paginated fashion:
 
 - We should make a request to URL in the form `https://api.github.com/repos/<repo>/commits`.
 - It responds with a JSON of 30 commits, and also provides a link to the next page in the `Link` header.
 - Then we can use that link for the next request, to get more commits, and so on.
