两行代码搞定js对象深浅拷贝

/**
* 遍历对象
* 1.判断是不是原始值
* 2.判断是数组还是对象
* 3.建立相应的数组或对象
* 递归
*/var obj=
{
name:"aaa",
age:23,
hobby:["basketball","music","coding"],
lover:{
name:"aaa",
age:23,
hobby:["sleep","movie","eat"]
}
}
var obj1={};function deepCopy(origin,target){
var target=target||{};//容错处理
for (var i in origin) {
if(origin.hasOwnProperty(i)){ //避免把原型上的属性遍历出来
if(typeof origin[i]=="object"){//先判断是引用值
if(origin[i] instanceof Array){//判断是数组
target[i]=[];
deepCopy(origin[i],target[i]);
}else{
target[i]={}; //判断是对象
deepCopy(origin[i],target[i]);
} }else{//原始值直接赋值
target[i]=origin[i];
}
}
} return target;//返回拷贝后的对象
}deepCopy(obj,obj1);
console.log(obj,obj1);

function deepCopy(origin,target){

}
}
