Regular Job
Regular Job(), this is the default job that is used by scopes. See Job for more info.
By default I mean: Unless you explicitly created SupervisedJob(), or used supervisedScope. Then you are using regular Job.
Job is created even when you don't create it by hand methods like runBlocking(),async(),launch() create it behind the scenes. Each co-routine has Job instance see Coroutine Diagram for visualization.
The importance of this Job is that it creates Exception/Cancellation Behavior with Regular Job
