We use reflect as the example:
package main
import (
"fmt"
"reflect"
)
func main() {
hth:=map[string]string{"a":"1","b":"c"}
n1 :=array_shift(hth)
fmt.Println(n1)
fmt.Println(hth)
}
func array_shift(abc interface{}) (interface{}){
key := reflect.ValueOf(abc).MapKeys()[0].String()
v := reflect.ValueOf(abc)
i := v.MapIndex(reflect.ValueOf(key))
v.SetMapIndex(reflect.ValueOf(key),reflect.Value{})
return i
}
Result:
1 map[b:c]
