What are async calls and how do they affect the call stack?

What are async calls and how do they affect the call stack?

Async calls allow functions to run in the background without blocking the main thread, affecting the call stack by not adding to it immediately.

Can you explain how the call stack works with async functions?

Sure! The call stack keeps track of function calls. With async functions, the call stack can continue executing other code while waiting for the async operation to complete.

What happens if I have multiple async calls?

If you have multiple async calls, they can run concurrently, allowing your program to handle other tasks while waiting for each async operation to finish.

Are there any downsides to using async calls?

Yes, async calls can lead to callback hell if not managed properly, making code harder to read and maintain.
