```val jobA = Job() val jobB = GlobalScope.launch(...

[Simon Lin]

val jobA = Job()
val jobB = GlobalScope.launch(jobA) {
    delay(1000L)
    println("World!")
}

What is the different between jobA and jobB?
If I would like to cancel the Job, which one need to be called? jobA.cancel() or jobB.cancel() ?
