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: always use try/catch for error handling, avoid nesting async functions, and keep your async functions small.

Can you explain why it's important to avoid nesting async functions?

Nesting async functions can lead to callback hell, making your code harder to read and maintain. It's better to use flat structures.

What should I do if I have multiple async calls that depend on each other?

You can use Promise.all() to run them concurrently if they don't depend on each other, or chain them with await if they do.

Are there any performance considerations I should be aware of?

Yes, excessive use of async/await can lead to performance issues if not managed properly, especially with many concurrent operations.
