• LaunchedEffect and rememberCoroutineScope() are attached to the composable lifecycle. The jobs will be cancelled if the composable leaves its composition.
• viewModelScope is attached to the ViewModel lifecycle. The jobs will be cancelled if the viewModel is cleared.

Composable Lifecycle

• Configuration changes and navigating to another screen can let the composable leave the composition.
• See Lifecycle of composables.

ViewModel Lifecycle

• A ViewModel, including the one returned by viewModel(), is scoped to either an Activity or Fragment, not the Composable where viewModel() was called. See viewModel.
• See viewModel for the following statement.

Note: Due to their lifecycle and scoping, you should access and call ViewModel instances at screen-level composables, that is, close to a root composable called from an activity, fragment, or destination of a Navigation graph. You should never pass down ViewModel instances to other composables, pass only the data they need and functions that perform the required logic as parameters.
