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 Supervisor-Job, 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
