golang中map的索引验证

package main

import (
	"fmt"
)

func main() {
	var scoreMap = make(map[string]int, 6)
	scoreMap["鱼香肉丝"] = 17
	scoreMap["溜肉段"] = 15
	value, ok := scoreMap["宫保鸡丁"]
	fmt.Println(value, ok)
	if ok {
		fmt.Println("宫保鸡丁还可以点", value)
	} else {
		fmt.Println("宫保鸡丁买完了")
	}
}

 

value,ok = map[index]
if  ok {
}else {
}
