How can I use async iterables in Node.js?

You can use async iterables in Node.js to handle asynchronous data streams. They allow you to work with data that arrives over time, like reading files or fetching data from APIs.

Can you give me an example of how to implement it?

Sure! Here's a simple example:

async function* asyncGenerator() {
    for (let i = 0; i < 5; i++) {
        await new Promise(resolve => setTimeout(resolve, 1000)); // Simulate async operation
        yield i;
    }
}

(async () => {
    for await (const value of asyncGenerator()) {
        console.log(value);
    }
})();

This code creates an async generator that yields numbers 0 to 4 with a delay.

What are the benefits of using async iterables?

Async iterables provide a clean and efficient way to handle asynchronous data, allowing you to use for await...of loops, which makes your code easier to read and maintain.

Are there any limitations I should be aware of?

Yes, async iterables can only be used in environments that support ES2018 or later. Additionally, they may not be as performant as traditional iterables for synchronous data.
