What are the differences between async iterables and streams?

What are the differences between async iterables and streams in JavaScript?

Async iterables and streams are both used for handling asynchronous data, but they have different use cases. Async iterables allow you to iterate over data asynchronously using a for-await-of loop, while streams are more about processing data in chunks, often used for I/O operations.

Can you give me an example of when to use each?

Sure! Use async iterables when you want to work with a sequence of values that can be awaited, like fetching data from an API. Use streams when dealing with large files or data that you want to process in chunks, like reading a file line by line.

Are there performance differences between them?

Yes, streams can be more efficient for large data sets since they process data in chunks, reducing memory usage. Async iterables may be simpler for smaller datasets or when you need to work with each item individually.

Which one is easier to implement?

Async iterables are generally easier to implement and understand, especially for those familiar with the async/await syntax. Streams can be more complex due to their need for handling backpressure and chunked data.
