Golang copy map object properties to another map object (js destructing equivalent)

copy_object_properties.go

package main

import "fmt"

func main() {
	person := map[string]interface{}{
		"name":   "test",
		"age":    13,
		"school": "stanford",
	}
  
	student := map[string]interface{}{
		"school": "harvard",
	}

	for k, v := range person {
		if _, ok := student[k]; !ok {
			student[k] = v
		}
	}

	fmt.Println(student) // map[age:13 name:test school:harvard]
}
