Today, I will show you how do I convert a map to array in golang, as above mentioned I’m going to use for and append() method.

Let’s start our Golang convert map to array example

main.go

package main

import (
	"fmt"	
)

func main() {
	m := make(map[int]string)

  m[1] = "a"
  m[2] = "b"
  m[3] = "c"
  m[4] = "d"
  
  v := make([]string, 0, len(m))
  
  for  _, value := range m {
     v = append(v, value)
  }
	fmt.Println(v)
	
}

In the above example, we have converted the map to array and printed in golang console. let’s check the output.

Output
