What are async iterators in Node.js?

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() {
    yield 'Hello';
    yield 'World';
}

const iterator = asyncGenerator();

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

What are some use cases for async iterators?

Async iterators are useful for handling streams of data, such as reading files, making API calls, or processing data from databases in a memory-efficient way.

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

Async iterators were introduced in Node.js 10.0.0, so they are supported in all later versions.
