What are the differences between async iterables and promises?

What are the differences between async iterables and promises?

Async iterables allow you to iterate over data asynchronously, while promises represent a single value that may be available now or in the future.

Can you give me an example of when to use async iterables?

Sure! Use async iterables when you need to process a stream of data, like reading lines from a file or fetching data from an API in chunks.

What about promises? When should I use them?

Promises are great for handling single asynchronous operations, like fetching data from an API where you expect one response.

Are there any performance differences between the two?

Yes, async iterables can be more efficient for handling large datasets since they allow processing data as it arrives, rather than waiting for all data to be available.
