What are async iterators in JavaScript?

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.

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

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);
}

What is the difference between async iterators and regular iterators?

The main difference is that async iterators handle asynchronous data, using await to pause execution until the next value is available, while regular iterators work with synchronous data.

Are async iterators supported in all browsers?

Async iterators are supported in modern browsers, but you should check compatibility for older versions or use a transpiler like Babel for broader support.
