What are some real-world examples of asynchronous iteration?

Asynchronous iteration is commonly used in programming, especially in JavaScript. For example, fetching data from an API can be done using async iterators, allowing you to process data as it arrives without blocking the main thread.

Can you give me a specific code example?

Sure! Here's a simple example using async iterators in JavaScript:

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

(async () => {
    for await (const item of fetchData()) {
        console.log(item);
    }
})();

What are the benefits of using async iteration?

The main benefits include improved performance, non-blocking operations, and the ability to handle large data streams efficiently.

Are there any drawbacks?

Yes, some drawbacks include increased complexity in code and potential difficulties in error handling compared to synchronous iteration.
