What are the pros and cons of using promises instead of callbacks?

Here are the pros of using promises over callbacks:

• Better defined and organized control flow of asynchronous logic.
• Highly reduced coupling.
• We have integrated error handling.
• Enhanced readability.

Cons of using Promises over callbacks:

• It kills the purpose of asynchronous non-blocking I/O.
• Only one object can be returned.
• We cannot return multiple arguments.
