Copy an array by value and reference into another array

The values "Japan", "Australia", "Germany" are assigned to strArray1. strArray1 is then assigned to strArray2, which means that a copy of those values is created. The reassignment of the strArray1 to strArray3 from a value assignment to a reference assignment.
package main

import "fmt"

func main() {

	strArray1 := [3]string{"Japan", "Australia", "Germany"}
	fmt.Printf("strArray1: %v\n", strArray1)
	strArray2 := strArray1 // data is passed by value (copied)
	fmt.Printf("strArray2: %v\n", strArray2)
	strArray1[0] = "Canada"
	fmt.Printf("strArray1: %v\n", strArray1)
	fmt.Printf("strArray2: %v\n", strArray2)

	strArray3 := &strArray1
	fmt.Printf("strArray3: %v\n", strArray3)
	fmt.Printf("&strArray3: %v\n", &strArray3)
	fmt.Printf("*strArray3: %v\n", *strArray3)
