How can I handle errors in async code effectively?

You can use try-catch blocks within async functions to catch errors. Additionally, you can handle rejections with .catch() on promises.

What about using async/await? Does it change how I handle errors?

Yes, using async/await allows you to write cleaner code. You can wrap your await calls in a try-catch block to handle errors.

Are there any best practices for error handling in async code?

Some best practices include logging errors, providing user-friendly messages, and using centralized error handling.

Can you give me an example of error handling in a real async function?

Sure! Here's a simple example:

async function fetchData() {
    try {
        const response = await fetch('https://api.example.com/data');
        if (!response.ok) throw new Error('Network response was not ok');
        const data = await response.json();
        return data;
    } catch (error) {
        console.error('Fetch error:', error);
    }
}
