difference CoroutineScope(Dispatchers.IO + Job()) and CoroutineScope(Dispatchers.IO) + Job()
I wonder what is the difference between these 2 ways of creating scope?
1:
val scope1 = CoroutineScope(Dispatchers.IO + Job())

2
val scope2 = CoroutineScope(Dispatchers.IO) + Job()

I noticed that it both creates 1 CoroutineScope. is there any difference between these 2 ways of creating?
