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?
