Notes for dirt simple JS inheritance

BaseClass.js

function BaseClass(child) {
    var key;
    child = child || {};
    this.base = {};
    for (key in this) {
        this.base[key] = this[key];
    }
    for (key in child) {
        this[key] = child[key];
    }
    return this;
}

BaseClass.Abstract = function () {
    throw Error('[BaseClass] Abstract method was called without definition.');
};

BaseClass.Stub = function () {};
