What are the differences between async generators and sync generators?

What are the differences between async generators and sync generators?

Async generators allow you to yield promises, enabling asynchronous iteration, while sync generators yield values directly.

Can you give me an example of each?

Sure! A sync generator can be defined using function* and yields values directly. An async generator uses async function* and yields promises.

When would I use async generators over sync generators?

Use async generators when dealing with asynchronous data sources, like fetching data from an API, to handle data as it arrives.

Are there any performance differences between them?

Yes, async generators may have overhead due to promise handling, but they are essential for non-blocking operations.
