第7章 for of值遍历

ES6新增了​​for...of​​循环语法。

//遍历数组
var team = ["师父", "大师兄", "二师兄", "沙师弟", "小白龙"];
for(var v of team){
    console.log(v);
}
//也可以遍历字符串
var str = "zhangsan";
for(var v of str){
    console.log(v);
}
//for of不能遍历对象{} 
var person = {"nickname":"老三", "age":30, "sex":"男"};
for(var v of person){ //报错
    console.log(v);
}
