前端js也有引用类型的概念

前端js也要考虑引用类型的概念

代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<script>
    function changeName() {
        const list = [];
        const person1 = {name: "zhangsan", age: 21};
        const person2 = {name: "lisi", age: 22};
        const person3 = {name: "wangwu", age: 23};
        //修改前记录
        console.log("person2.name:" + person2.name);
        //下面模仿逻辑操作
        list.push(person1)
        list.push(person2)
        list.push(person3)
        const demo = list[1];
        //修改名称
        demo.name = 'jack';
        //验证结果
        console.log("person2.name:" + person2.name);
    }
</script>
<body>

<div>
    <button onclick="changeName()">点击</button>
</div>
</body>
</html>

结果：

person2.name:lisi
person2.name:jack
