js 封装结构示例

示例1：

class Student {

    static type = "person";
    name = "";

    constructor(name) {
        console.log("start")
        this.name = name;
    }

    show() {
        console.log("show")
    }
}

var stu = new Student("hester");
console.log(stu.name)
console.log(Student.type)
stu.show();

示例2：

var Student = (function () {
    function Student(name) {
        console.log("start")
        this.name = name;
    }
    Student.type = "person";
    Student.prototype.show = function () {
        console.log("show");
    };
    return Student;
}());

var stu = new Student("hester");
console.log(stu.name)
console.log(Student.type)
stu.show();
