What are the best practices for using async/await with fetch?

When using async/await with fetch, ensure to handle errors properly, use try/catch blocks, and avoid blocking the main thread.

Can you give an example of how to implement that?

Sure! Here's a simple example:

async function fetchData(url) {
    try {
        const response = await fetch(url);
        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);
    }
}

What should I do if the fetch fails?

In the catch block, you can log the error, show a user-friendly message, or retry the fetch operation depending on your needs.

Are there any performance considerations I should be aware of?

Yes, avoid making too many concurrent fetch requests. You can use Promise.all for multiple requests, but be cautious of rate limits.
