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
[c d a b]
