es6数组对象新方法总结

1，数组的合并

var a=["校长"，"老师"];
var b="我";
var c=[...a,b];
c=["校长"，"老师","我"];

2,对象,()里面实现对象的组装

var a=((
    b={},
    b.name="小花",
    b
));
console.log(a)    //{name:'小花'}

3,对象的映射

var a={"name":"xiaoming","age":12,"sex":"man"};
var {name,sex}=a;
console.log(name);    //"xiaoming"
console.log(sex);     //"man"
