What are the best practices for using async/await in JavaScript?

What are the best practices for using async/await in JavaScript?

Some best practices include handling errors with try/catch, avoiding blocking code, and using async/await only in async functions.

Can you explain why I should avoid blocking code?

Blocking code can freeze the event loop, making your application unresponsive. Use async/await to keep it non-blocking.

What should I do if I have multiple asynchronous calls?

You can use Promise.all to run them concurrently, or await them sequentially if the order matters.

Are there any performance considerations I should be aware of?

Yes, while async/await is easier to read, excessive use can lead to performance issues. Profile your code to find bottlenecks.
