What are async iterators in TypeScript?

Async iterators are a way to handle asynchronous data streams in TypeScript, allowing you to iterate over data that is received over time.

Can you give me an example of how to use async iterators?

Sure! You can create an async iterator using the async function* syntax. Here's a simple example:

async function* asyncGenerator() {
    for (let i = 0; i < 5; i++) {
        yield new Promise(resolve => setTimeout(() => resolve(i), 1000));
    }
}

const iterator = asyncGenerator();

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

What are the benefits of using async iterators?

Async iterators simplify working with asynchronous data, making your code cleaner and easier to read, especially when dealing with streams or APIs.

Are there any limitations to async iterators?

Yes, async iterators can only be used in environments that support ES2018 or later, and they may not be as widely supported in older browsers.
