JS基础 - 数据类型 - 栈区和堆区

简单数据类型  -- 栈区

var name = "张三";
var newName = name;

name = "李四";
console.log(name); //李四
console.log(newName); //张三

复杂数据类型 -- 堆区

var obj = {
    name: "张三",
    age: 34
};
var newObj = obj;

obj.name = "李四";
obj.age = 100;

console.log(obj); //{name: "李四", age: 100}
console.log(newObj); //{name: "李四", age: 100}
