In the SubClass constructor, object masquerading is used to inherit the color property from BaseClass.

Then prototype chaining is used to inherit the methods of BaseClass.

function BaseClass(sColor) {
    this.color = sColor;
}

BaseClass.prototype.sayColor = function () {
    alert(this.color);
};

function SubClass(sColor, sName) {

    BaseClass.call(this, sColor);
    this.name = sName;
}

SubClass.prototype = new BaseClass();

SubClass.prototype.sayName = function () {
    alert(this.name);
};

var objA = new BaseClass("red");
var objB = new SubClass("blue", "MyName");
objA.sayColor();
objB.sayColor();
objB.sayName();
