What are the best practices for using async iterators in TypeScript?

When using async iterators in TypeScript, it's important to ensure proper error handling, use of the for await...of loop, and to keep your iterators simple and focused.

Can you explain how to handle errors in async iterators?

Certainly! You can handle errors in async iterators by using try-catch blocks within the for await...of loop to catch any exceptions that occur during iteration.

What are some common use cases for async iterators?

Common use cases include processing streams of data, handling API responses that return data over time, and reading files asynchronously.

How do async iterators compare to regular iterators?

Async iterators allow you to work with asynchronous data sources, enabling you to pause execution until the next value is available, while regular iterators work with synchronous data.

Can you provide a code example of an async iterator?

Sure! Here's a simple example:

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

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