Copy code
coroutineScope { launch(IO) { ... } }
Is not really idiomatic. It does the same as
Copy code
withContext(IO) { ... }
Also, IO context is used to bridge blocking code to suspend functions. In your case, you are using an asynchronous function underneath, so there is no need of the IO context, so no need of the
withContext
too

Using
withContext
doesn’t create a
CoroutineScope
, does it ? If it doesn’t, then
coroutineScope
is better, so we have children coroutines and not sibling. Am I wrong ?

It does (look at the receiver in the lambda of withContext). But you don't even need a coroutine scope as you don't really need to launch any coroutine in
sendRequestAndPrintResultSuspendable
, because you can just call the other suspending function directly.
