// Arrays
var dogNames = ["Miki", "Miki1", "Miki2"]
dogNames.first // Miki
dogNames.last // Miki2
dogNames.count // 3
dogNames[1] // Miki1
dogNames.append("Miki3") // "Miki", "Miki1", "Miki2", "Miki3"
dogNames.insert("Miki4", at: 3) // "Miki", "Miki1", "Miki2", "Miki4", "Miki3"
dogNames.removeAll() // empty
var emptyDoubles: [Double] = [] // create an empty array by specifying the Element type
