What are the differences between Promises and Async Iterators?

What are the differences between Promises and Async Iterators?

Promises are used for handling asynchronous operations, while Async Iterators allow you to iterate over asynchronous data streams.

Can you give me an example of how to use an Async Iterator?

Sure! Here's a simple example:

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

const iterator = asyncGenerator();

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

How do I convert a Promise to an Async Iterator?

You can create an Async Iterator that resolves the Promise and yields its value. Here's an example:

async function* promiseToAsyncIterator(promise) {
    yield await promise;
}

When should I use Async Iterators instead of Promises?

Use Async Iterators when you need to handle multiple asynchronous values over time, like streaming data.
