Create 10 decks in a functional for-loop

functional-forloop.swift

// Swift 3

struct Deck {
    var name: String
}

// usual way;
var decks : [Deck] = [Deck]()
for idx in 1...10 {
    decks.append( Deck.init(name: "#\(idx)") )
}

// functional way
let decks = (1...10).enumerated().map({ (offset, element) in
    return (Deck.init(name: "Deck.\(offset)"))
})
