How can I handle API errors in my asynchronous application?

You can handle API errors by using try-catch blocks in your async functions and implementing error handling strategies.

What are some common error handling strategies?

Common strategies include retrying requests, logging errors, and providing user feedback when an error occurs.

How do I implement a retry mechanism?

You can implement a retry mechanism by using a loop that attempts the request a specified number of times before failing.

Can you show me a code example?

Sure! Here's a simple example using JavaScript:

async function fetchData(url) {
    for (let i = 0; i < 3; i++) {
        try {
            const response = await fetch(url);
            if (!response.ok) throw new Error('Network response was not ok');
            return await response.json();
        } catch (error) {
            console.error('Fetch attempt failed:', error);
        }
    }
    throw new Error('Failed to fetch data after 3 attempts');
}
