    return "male";
  }
}

class MaleHuman extends Human {
  constructor(name) {
    super(name, Human.getGenderMale());
  }
}

class FemaleHuman extends Human {
  constructor(name) {
    super(name, Human.getGenderFemale());
  }

AjaxContent Updated

JavaScript Object Model - OO Programming

JavaScript is a C++-like scripting language and like most of its relatives let the programmers to write in both object oriented and procedural style. But there is a big difference between JavaScript and other popular OO languages such as C++ and Java which are class based languages.
OO languages are either class based or prototype based. JavaScript is one of prototype based languages out there.
There are lots of references and tutorials about OO programming in JavaScript in the Net. Most of them are so useful and explain a single aspect of OO programming in the language. Some are based on a particular framework such as Prototype, JQuery ... while some explain the pure JavaScript rules.If you are curious to read yet another nice article about JavaScript Object Model, I strongly suggest you to spend 15 minutes to read JavaScript's class-less objects by Stoyan Stefanov.
The article explains the dynamic features of the JavaScript and explains different ways to implement inheritance in the language and then compare them with Java's way.
