What are async iterators in JavaScript?

Async iterators are a way to work with asynchronous data streams in JavaScript, allowing you to iterate over data that is fetched asynchronously.

How do they differ from regular iterators?

Regular iterators work with synchronous data, while async iterators use the async and await keywords to handle data that arrives over time.

Can you give me an example of using async iterators?

Sure! Here's a simple example:

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

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

What are some use cases for async iterators?

They are useful for handling streams of data, such as reading files, fetching data from APIs, or processing events in real-time.
