How do Promises, Async\Await contribute to the Node's non-blocking async event-driven architecture?

Hi, folks!

A quick question for you all, that has been bugging me lately.

How do Callback, Promise, Async\Await complement Node's non-blocking functionality

Please look at the screenshot from one of the courses I have been following for Asynchronous features of JS from the LinkedIn Learning course viz. Learning ECMAScript 6 (ES6).

I Look forward to your insights.

Thank you!

Best,
Ihtisham
