How does async/await affect performance in TypeScript?

How does async/await affect performance in TypeScript?

Async/await can simplify asynchronous code, but it may introduce some performance overhead compared to traditional callbacks.

What kind of overhead are we talking about?

The overhead mainly comes from the creation of promises and the additional stack frames. However, the impact is often negligible for most applications.

Are there scenarios where I should avoid using async/await?

Yes, in performance-critical sections where every millisecond counts, you might prefer using callbacks or traditional promise chaining.

Can you give an example of a performance issue with async/await?

Sure! If you have a tight loop that makes multiple asynchronous calls, using async/await can lead to slower execution compared to using Promise.all.
