Create An Array with Default Values

// Create an Array of Strings
var appleProgrammingLanguages: [String] = ["Swift", "Objective-C"]

//  Thanks to Swift’s type inference, you don’t have to write the type of the array if you’re initializing it with an array literal containing values of the same type
var otherProgrammingLanguages = ["Javascript", "PHP"]

// Create an Array of Int
var randomNumbers: [Int] = [0, 5, 15, 43]

// Create an Array with default values
var arrayOfThreeElements = [Int](count: 3, repeatedValue: 1)

// Create a new Array by adding two arrays together 
var myProgrammingLanguages = appleProgrammingLanguages + otherProgrammingLanguages
print(myProgrammingLanguages)
