Return: Quiz III in Scala

Quiz: What would this code produce if we were to copy-paste it in a code editor and run it?

def getGreeting(name: String): String = {
	println("Hey, " + name)
}

def mainFunction(): Unit = {
	val greeting = getGreeting("Andy")
	println(greeting)
}

Important Note:

Do not use an actual code editor to get the answer! It would defy the whole purpose of the quiz!
