Remembering Things

Variables let you name values and reuse them later.

example.go

name := "Gopher"
age := 10
happy := true

Two characters: :=. That's Go's short variable declaration. No type keywords needed. Go looks at the value and picks the type for you. "Gopher" makes name a string. 10 makes age an int. true makes happy a bool.

>_Exercise

Exercise: Order Receipt

Create two variables using :=:

product with value "Coffee"
price with value 5

Print each on its own line so the output is exactly:

example.go

Coffee
5

Key Takeaway

Next UpValues that never change.

package main

import "fmt"

func main() {
	// Create a product variable with value "Coffee"
	// Create a price variable with value 5

	fmt.Println(product)
	fmt.Println(price)
}

Output

$ go run main.go
