What are the best practices for using async functions in JavaScript?

Some best practices include using try/catch for error handling, avoiding blocking code, and keeping functions small.

Can you explain why avoiding blocking code is important?

Avoiding blocking code ensures that your application remains responsive, allowing other operations to run concurrently.

What should I do if an async function fails?

You should use try/catch blocks to handle errors gracefully and provide fallback mechanisms or user notifications.

Are there any performance considerations I should be aware of?

Yes, consider the number of concurrent async operations and avoid overwhelming the event loop, which can lead to performance issues.
