How do async generators differ from promises in JavaScript?

How do async generators differ from promises in JavaScript?

Async generators allow you to yield multiple values over time, while promises resolve to a single value.

Can you give me an example of an async generator?

Sure! Here's a simple async generator:

async function* asyncGen() {
    yield 1;
    yield 2;
    yield 3;
}

You can use it with a for await...of loop.

What are the advantages of using async generators?

Async generators are great for handling streams of data, allowing you to process values as they arrive without waiting for all of them.

Are there any scenarios where I should prefer promises over async generators?

Yes, if you only need a single value or a simple asynchronous operation, promises are more straightforward and easier to use.
