How does asynchronous code affect JavaScript performance?

Asynchronous code can improve performance by allowing non-blocking operations, which means other code can run while waiting for tasks like network requests.

Can you give an example of when async code is beneficial?

Sure! For instance, when fetching data from an API, using async code allows the UI to remain responsive while the data is being retrieved.

Are there any downsides to using async code?

Yes, one downside is that it can make code harder to read and debug, especially if not managed properly with promises or async/await.

How can I manage async code effectively?

You can use async/await syntax for better readability and error handling, and libraries like Axios for easier API calls.
