What are the benefits of using async generators in JavaScript?

Async generators allow you to work with asynchronous data streams more efficiently, enabling better handling of data that arrives over time.

Can you give me an example of how to use async generators?

Sure! You can define an async generator using the async function* syntax. For example:

async function* fetchData() {
    const data = await fetch('https://api.example.com/data');
    const json = await data.json();
    for (const item of json) {
        yield item;
    }
}

This allows you to yield data as it is fetched.

What makes async generators different from regular generators?

The key difference is that async generators can pause execution and wait for promises to resolve, while regular generators only yield values synchronously.

Are there any performance benefits to using async generators?

Yes, async generators can improve performance by allowing you to process data as it arrives, rather than waiting for all data to be available before starting processing.
