Knew there’d be a good reason, I just hadn’t gotten that far yet. Thanks for posting.

Isn’t a map, at least in part, a function from key to value? Isn’t an array, at least in part, a function from integer to value?

Here’s something to contemplate

def english(n: Int) = n match {
case 0 => “zero”
case 1 => “one”
case 2 => “two”
}

val spanish = Map(
0 -> “cero”,
1 -> “uno”,
2 -> “dos”
)

val french = Array(“zero”, “un”, “deux”)

def translate(n : Int, language : Int => String) = language(n)

println(translate(0, english))
println(translate(1, spanish))
println(translate(2, french))
