Simple inheritance demonstration in Javascript

EPIC_RAINBOW_DEMO.js

// A "class"
function MyEpicEntity(name)
{
    if(name)
    {
        this.name = name;
    }

    this.epic = true; // obvsly...
}

// Create the prototype, an object with one sole attribute named sayName that happens to be a function
MyEpicEntity.prototype =
{
    sayName: function()
    {
        console.log("MyEpicEntity with name: " + this.name);
    }
};

// Since we replaced the prototype with a newly created object, we need to correct its constructor reference
// to its intended value.
MyEpicEntity.prototype.constructor = MyEpicEntity;

// A "class" that inherits from MyEpicEntity
function MyAwesomeEntity(name, level)
{
    // Call our parent constructor
    MyEpicEntity.call(this, name);

    this.awesomeLevel = level;
}

// Set up the inheritance and fix the constructor reference
MyAwesomeEntity.prototype = new MyEpicEntity();

// Add a method to the prototype of MyAwesomeEntity
MyAwesomeEntity.prototype.getLevel = function()
{
    return (this.awesomeLevel > 9000)? "It's over 9000!!!11" : this.awesomeLevel;
};

MyAwesomeEntity.prototype.constructor = MyAwesomeEntity;

// You are now free to create new "instances" of MyAwesomeEntity while reaping the benefits of having implemented
// MyEpicEntity
var mae = new MyAwesomeEntity("Jim-Bob Bobson", 5);
console.log(mae.getLevel()); // 5
mae.sayName(); // "MyEpicEntity with name: Jim-Bob Bobson"
