这是由荷兰程序员 Gabor de Mooij 提出的一种比较简单的方法。Gabor de Mooij 称之为 minimalist approach。现摘录如下：

定义一个 Foo 类

var Foo = {
    createNew: function(){
        var instance = {};
        instance.description = "A new class instance";
        instance.bar = function() { console.log(instance.description)};
        return instance;
    }
}

创建一个 Foo 实例

var foo = Foo.createNew();
foo.bar();

类的继承

var NewFoo = {
    createNew = function(){
        var instance = Foo.createNew();
        instance.title = "A new title";
        instance.newBar = function(){
            alert(instance.description);
        };
    }
}

私有方法和属性

var Foo = {
    createNew: function(){
        var instance = {};
        instance.description = "A new class instance"; //description 是私有的，只有通过 bar() 来访问
        instance.bar = function() { console.log(instance.description)};
        return instance;
    }
}

静态成员变量

var Foo = {
    id: 101010; // id 在多个实例间共享
    createNew: function(){
        var instance = {};
        instance.description = "A new class instance"; //description 是私有的，只有通过 bar() 来访问
        instance.bar = function() { console.log(instance.description)};
        return instance;
    }
}

var foo1 = Foo.createNew();
var foo2 = Foo.createNew();
foo2.id = 233333;
console.log("Foo id:"+foo1.id);
