JavaScript创建对象的方式：
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<script>
// 构造方法创建JavaScript对象
function Stu(naem,sex,age){
this.name = name;
this.sex = sex;
this.age = age;
}
let stu = new Stu('小白','男',20);
console.log(stu);
// 函数创建对象
function cer(name,age){
var obj = new Object();
obj.name = name;
obj.age = age;
return obj;
}
let cer1 = cer('天达',22);
console.log(cer1);
// 字面量创建对象
let arr = {name:'天弘',fun:function(){return this.name}}
console.log(arr.name);
</script>
