How to create a copy of the map in Golang

// Golang program to create a copy of the map

package main

import "fmt"

func main() {
	var CountryCode = make(map[string]int)

	CountryCode["ind"] = 101
	CountryCode["aus"] = 102
	CountryCode["eng"] = 103
	CountryCode["pak"] = 104
	CountryCode["usa"] = 105

	var CloneMap = CountryCode

	fmt.Println("CountryCode: ", CountryCode)
	fmt.Println("CloneMap   : ", CloneMap)
}

In the main() function, we created a CountryCode map using make() function to store country code of specified country. Map store items in KEY/VALUE pair. Then we create a copy of the CountryCode map using the assignment operator and then print both maps
