Can you explain async iterators in Node.js with examples?

Can you explain async iterators in Node.js with examples?

Sure! Async iterators allow you to work with asynchronous data streams in a more manageable way. For example, you can use them to read files or fetch data from APIs.

Can you show me a code example of using async iterators?

Absolutely! Here's a simple example:

async function* asyncGenerator() {
    yield 'Hello';
    yield 'World';
}

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

This code defines an async generator that yields 'Hello' and 'World'.

What are some use cases for async iterators?

Some common use cases include reading large files line by line, processing data from streams, and handling multiple API requests concurrently.

Are async iterators supported in all Node.js versions?

Async iterators are supported in Node.js version 10 and above, so make sure your environment is up to date!
