Pros of promises:
* Avoid callback hell: Promises provide a cleaner, more readable way to handle asynchronous operations.
* Chaining: Enables chaining of multiple asynchronous operations.
* Error handling: Centralized error handling with .catch().
Cons of promises:
* Complexity: Slightly more complex syntax compared to simple callbacks.
* Overhead: May introduce some overhead due to additional abstraction.
