What are async iterators in Node.js?

Async iterators are a way to work with asynchronous data streams in Node.js, allowing you to iterate over data that is fetched asynchronously.

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

Sure! You can create an async iterator using the Symbol.asyncIterator method. 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;
    }
}

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

What are the benefits of using async iterators?

Async iterators provide a clean and efficient way to handle asynchronous data, making your code easier to read and maintain. They also allow for better control over flow and error handling.

Are async iterators supported in all versions of Node.js?

Async iterators are supported starting from Node.js version 10.0.0, so make sure your environment is up to date.
