Variables and Types

Go is a statically defined language (like Java, C++)

// 'string' here tells the go compiler that this variable will only be of string type 
var cards string = "Ace of Spades"

Other types:

bool //(true|false)
string
int
float64

A more efficient way to declare a variable and let go figure out the type of data:

card := "Ace of Spades"

Can also declare a variable and then define it

var deckSize int
deckSize = 52

To define a method return of type string:

func newCard() string {
  return "Five of Diamonds"
}

Adding Variable Values to Formatted String (%d, %v)​

t.Errorf("Expected deck length is 52, but got %d", len(d))
