Iterating over all the keys of a map
https://play.golang.org/p/JGZ7mN0-U- for k, v := range m { fmt.Printf(“key[%s] value[%s]\n”, k, v) } or for k := range m { fmt.Printf(“key[%s] value[%s]\n”, k, m[k]) } Go language specs for for statements specifies that the first value is the key, the second variable is the value, but doesn’t have to be present.
