Return: Quiz I in Scala in Scala

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

def getDouble(n: Int): Int = {
	println(n * 2)
}

def mainFunction(): Unit = {
	val result = getDouble(10)
	println(result)
}

Important Note:

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