How can I implement error handling in asynchronous retries?

You can implement error handling in asynchronous retries by using try-catch blocks and setting a maximum retry limit.

What if the error is due to a network issue?

In that case, you can add a delay before retrying and check for specific error types to handle them appropriately.

Can you show me a code example?

Sure! Here's a simple example in JavaScript using async/await:

async function fetchData(url, retries = 3) {
    for (let i = 0; i < retries; i++) {
        try {
            const response = await fetch(url);
            if (!response.ok) throw new Error('Network response was not ok');
            return await response.json();
        } catch (error) {
            if (i === retries - 1) throw error; // Rethrow if it's the last attempt
            await new Promise(res => setTimeout(res, 1000)); // Wait before retrying
        }
    }
}

What libraries can help with this?

Libraries like Axios for HTTP requests and libraries like retry-axios can simplify error handling and retries.
