What are JavaScript async iterators?

Can you explain what async iterators are in JavaScript?

Sure! Async iterators are a way to iterate over asynchronous data sources in JavaScript, allowing you to use the for await...of loop.

How do they differ from regular iterators?

Regular iterators work with synchronous data, while async iterators handle data that may not be available immediately, like fetching data from an API.

Can you give me an example of using async iterators?

Absolutely! 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 great for handling streams of data, like reading files, making API calls, or processing data from databases.
