25. 2. 11. Add method to Object class

Since all objects used in JavaScript are inherited from Object, all of the object can use the method added to Object.


Object.prototype.showValue = function () {

    alert(this.valueOf());

};



var str = "hello";

var iNum = 25;

str.showValue();

iNum.showValue();
