What are the best practices for using async in programming?

When using async, it's important to keep your code readable and maintainable. Use async/await for better flow.

Can you explain why async/await is preferred over callbacks?

Async/await makes your code look synchronous, which is easier to read and debug compared to nested callbacks.

Are there any common pitfalls to avoid when using async?

Yes, avoid blocking the event loop, and be cautious with error handling to prevent unhandled promise rejections.

How can I improve performance when using async functions?

You can improve performance by using concurrency with Promise.all for independent async calls, rather than awaiting each one.
