When should I use async iterators in JavaScript?

When should I use async iterators in JavaScript?

Async iterators are useful when you need to handle streams of data that are fetched asynchronously, like reading files or making API calls.

Can you give me an example of how to use async iterators?

Sure! You can use an async iterator with a function that fetches data in chunks, like this: async function* fetchData() { ... }.

What are the benefits of using async iterators over regular iterators?

Async iterators allow you to work with asynchronous data sources seamlessly, making your code cleaner and easier to manage.

Are there any performance considerations I should be aware of?

Yes, while async iterators can simplify code, they may introduce overhead due to the asynchronous nature, so it's important to profile your application.
