What is the difference between async and sync iterables?

What is the difference between async and sync iterables?

Async iterables allow for asynchronous iteration, meaning you can work with data that is fetched or generated over time, while sync iterables are processed all at once.

Can you give me an example of each?

Sure! A sync iterable could be an array of numbers, while an async iterable might be a stream of data from an API that you fetch one item at a time.

When would I use async iterables?

You'd use async iterables when dealing with operations that take time, like fetching data from a server, to avoid blocking the main thread.

Are there any performance differences?

Yes, async iterables can improve performance in I/O-bound tasks by allowing other operations to run while waiting for data.
