OOP in JavaScript - Part 3: Extending classes
After I've already covered normal and static classes, Part 3 is about extending classes. As before, basic knowledge in OOP and JavaScript is needed.First, let's create a class Human with setters and getters for the age:function Human(){ }Human.prototype._age = 0;Human.prototype.setAge = function(age){ if (typeof age != 'number') { throw('Invalid Age provided'); } this._age = age;};

As before basic OOP and JavaScript knowledge is needed.Generally writing and using static classes is monstly the same as normal classes. The difference is that you don't need to instantiate the object with new and you can't use prototyping nor this, since everything is in static context. One useful implementation for static classes is the Registry Design Pattern. First off we create the

OOP in JavaScript - Part 1: Writing classes
