Scala (6): variable-length parameters

You can pass random parameters to method by adding *, so that methods can take parameters of a repeated type

def capitalizeAll(args: String*) = {
  args.map { arg =>
    arg.capitalize
  }
} // capitalizeAll: (args: String*)Seq[String]

And then we can pass any length of variables.

capitalizeAll("rarity", "applejack")
// output: Seq[String] = ArrayBuffer(Rarity, Applejack)
