how to better understand `createDeferred`?

The doc says idle, what is the difference between requestIdleCallback and this? Should it be considerred as reactive version of requestIdleCallback? Moreover, after searching across gh and discord channels, there is few examples to show how to use createDeferred correctly. Is there any best-practice or learning resource about it?
