What are the differences between async iterators and promises in TypeScript?

Async iterators allow you to iterate over asynchronous data sources, while promises represent a single value that may be available now or in the future.

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

Sure! Here's a simple example:

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

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

How do promises work in TypeScript?

Promises in TypeScript are used to handle asynchronous operations. You create a promise using the Promise constructor and handle its result with .then() and .catch() methods.

Which one should I use for handling multiple asynchronous operations?

If you need to handle multiple asynchronous operations, async iterators can be more efficient as they allow you to process data as it arrives, rather than waiting for all operations to complete.
