<JavaScript> 稳妥构造函数模式与工厂模式的区别

function Person(name, age, job) {
    var o = new Object();
 
    // private members
    var nameUC = name.toUpperCase();

    // public members
    o.sayName = function() {
        alert(name);
    };
    o.sayNameUC = function() {
        alert(nameUC);
    };

    return o;
}

var person = Person("Nicholas", 32, "software Engineer");

person.sayName(); // "Nicholas"
person.sayNameUC(); // "NICHOLAS"

alert(person.name);  // undefined
alert(person.nameUC);  // undefined
