supervisorScope

The supervisorScope function also behaves a lot like coroutineScope: it creates a CoroutineScope that inherits from the outer scope and calls the specified suspend block in it. The difference is that it overrides the context’s Job with SupervisorJob, so it is not cancelled when a child raises an exception.

supervisorScope is mainly used in functions that start multiple independent tasks. - Kotlin Coroutines Deep Dive

• Waits for ALL children, even failing ones, even after some have failed and threw.
• Collects ALL exceptions from co-routines.

Notes

• Respects parent cancellation
