What are the best practices for using async generators in JavaScript?

When using async generators, it's important to handle errors properly, use for-await-of loops, and ensure proper resource management.

Can you give an example of how to implement an async generator?

Sure! Here's a simple example:

async function* fetchData() {
    for (let i = 0; i < 5; i++) {
        yield await fetch(`https://api.example.com/data/${i}`);
    }
}

This async generator fetches data from an API in a loop.

How do I handle errors in async generators?

You can use try-catch blocks within the async generator to catch errors. Additionally, ensure that the consumer of the generator also handles errors.

What are some common use cases for async generators?

Common use cases include streaming data from APIs, reading files in chunks, and handling multiple asynchronous tasks in a sequence.
