How does async/await affect JavaScript performance?

How does async/await affect JavaScript performance?

Async/await can improve code readability and maintainability, but it may introduce some performance overhead due to the creation of promises.

Is it always slower than using callbacks?

Not necessarily. While async/await can have some overhead, it often leads to cleaner code, which can be more efficient in the long run.

What are some best practices for using async/await?

Some best practices include handling errors with try/catch, avoiding blocking calls, and using Promise.all for concurrent operations.

Can you give an example of when to use async/await?

Sure! Use async/await when you have multiple asynchronous operations that depend on each other, like fetching data from an API.
