What are the performance benchmarks for async iterables?

What are the performance benchmarks for async iterables compared to regular iterables?

Async iterables can handle asynchronous data streams more efficiently, especially in I/O-bound operations. Benchmarks show they can outperform regular iterables in scenarios involving network requests or file reading.

Can you provide some specific benchmarks or examples?

Sure! For instance, when fetching data from an API, async iterables can process items as they arrive, reducing wait time significantly. In tests, async iterables showed a 30% improvement in speed for large datasets.

Are there any downsides to using async iterables?

Yes, while async iterables are great for I/O-bound tasks, they can introduce complexity in code and may have overhead in CPU-bound tasks. It's essential to evaluate the use case.

How do I implement async iterables in my project?

You can implement async iterables using the async keyword in your generator functions. Here's a simple example: async function* fetchData() { ... }.
