What are async iterators in Node.js and how do they work?

Async iterators in Node.js allow you to work with asynchronous data streams using a familiar iterator protocol. They enable you to iterate over data that is fetched asynchronously, such as reading files or making network requests.

Can you give me an example of using async iterators?

Sure! Here's a simple example: you can create an async generator function that yields values asynchronously. For instance, async function* fetchData() { yield await fetch('url1'); yield await fetch('url2'); } allows you to iterate over the fetched data.

How do I handle errors when using async iterators?

You can handle errors in async iterators using try-catch blocks within the async generator function. This way, you can catch any errors that occur during the asynchronous operations.

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

Async iterators are supported starting from Node.js version 10.0.0. Make sure to check your Node.js version to use this feature.
