map 無序問題請教

老師您好, 代碼如下： //申明的时候同时赋值 var mapVariables2 = map[string]int{ "Monday":1,"Tuesday":2,"Wednesday":3, "Thursday":4, } fmt.Println(mapVariables2) mapVariables3 := make(map[string]int) mapVariables3["Monday"] = 1 mapVariables3["Tuesday"] = 2 mapVariables3["Wednesday"] = 3 fmt.Println(mapVariables3)
