Simple Inheritance with JavaScript

You mean using a constructor like this?

var ClassA = function() {
    this.name = "class A";
}

And instantiating it like this?

var a = new ClassA();
ClassA.prototype.print = function() {
    console.log(this.name);
}

So that you can use it like this?

a.print();

Fairly simple, right? They do that above in the article.

Or were you meaning something different in regard to the inheritance?
