What are async iterators?

An async iterator is like a robot that gives you snacks one by one from a big jar, but it takes a little time to get each snack ready.

Imagine you have a jar full of your favorite cookies, and every time you ask for a cookie, the robot has to go find one, maybe even bake it. That means you don’t get all the cookies at once, just one by one, with little breaks in between. This is like how async iterators work: they give you values one at a time, but each value comes after some waiting or processing.

Let’s say you’re eating cookies from a jar. A normal iterator would be like opening the jar and just grabbing cookies, fast and easy. But an async iterator is more like asking the robot for a cookie every time, and it takes a few seconds to bring each one.

So instead of getting all the cookies right away, you get them one after another, with little pauses in between, just like how some apps load data slowly, showing you pieces at a time.
