examined a number of different JavaScript classical-inheritance-simulating techniques. Out of all the ones that I've looked at I think my favorites were the implementations employed by base2 and Prototype.

I wanted to go about extracting the soul of these techniques into a simple, re-usable, form that could be easily understood and didn't have any dependencies. Additionally I wanted the result to be simple and highly usable. Here's an example of what you can do with it:
var Person = Class.extend({
  init: function(isDancing){
    this.dancing = isDancing;
  },
  dance: function(){
    return this.dancing;
  }
});

var Ninja = Person.extend({
  init: function(){
    this._super( false );
  },
  dance: function(){
    // Call the inherited version of dance()
    return this._super();
  },
  swingSword: function(){
    return true;
  }
});



var p = new Person(true);

p.dance(); // => true



var n = new Ninja();

n.dance(); // => false

n.swingSword(); // => true



// Should all be true

p instanceof Person && p instanceof Class &&

n instanceof Ninja && n instanceof Person && n instanceof Class



A couple things to note about this implementation:



    * Creating a constructor had to be simple (in this case simply providing an init method does the trick).

    * In order to create a new 'class' you must extend (sub-class) an existing class.

    * All of the 'classes' inherit from a single ancestor: Class. Therefore if you want to create a brand new class it must be a sub-class of Class.

    * And the most challenging one: Access to overridden methods had to be provided (with their context properly set). You can see this with the use of this._super(), above, calling the original init() and dance() methods of the Person super-class.



I'm pleased with the result: It helps to enforce the notion of 'classes' as a structure, maintains simple inheritance, and allows for the super method calling.



Simple Class Creation and Inheritance



And here's the implementation (reasonably sized and commented well) - clocking in at around 25 lines. Feedback is welcome and appreciated.

// Inspired by base2 and Prototype

(function(){
  var initializing = false, fnTest = /xyz/.test(function(){xyz;}) ? /\b_super\b/ : /.*/;

  // The base Class implementation (does nothing)
  this.Class = function(){};
 
  // Create a new Class that inherits from this class
  Class.extend = function(prop) {
    var _super = this.prototype;
   
    // Instantiate a base class (but only create the instance,
    // don't run the init constructor)
    initializing = true;
    var prototype = new this();
    initializing = false;
   
    // Copy the properties over onto the new prototype
    for (var name in prop) {
      // Check if we're overwriting an existing function
      prototype[name] = typeof prop[name] == "function" &&
        typeof _super[name] == "function" && fnTest.test(prop[name]) ?
        (function(name, fn){
          return function() {
            var tmp = this._super;
           
            // Add a new ._super() method that is the same method
            // but on the super-class
            this._super = _super[name];
           
            // The method only need to be bound temporarily, so we
            // remove it when we're done executing
            var ret = fn.apply(this, arguments);       
            this._super = tmp;
           
            return ret;
          };
        })(name, prop[name]) :
        prop[name];
    }
   
    // The dummy class constructor
    function Class() {
      // All construction is actually done in the init method
      if ( !initializing && this.init )
        this.init.apply(this, arguments);
    }
   
    // Populate our constructed prototype object
    Class.prototype = prototype;
   
    // Enforce the constructor to be what we expect
    Class.constructor = Class;

    // And make this class extendable
    Class.extend = arguments.callee;
   
    return Class;
  };
})();



In my opinion the two trickiest parts are the "initializing/don't call init" and "create _super method" portions. I want to cover those briefly so that you will have a good understanding of what's being achieved in this method.



Initialization



In order to simulate inheritance with a function prototype we use the traditional technique of creating an instance of the super-class function and assigning it to the prototype. Without using the above it would look something like this:

function Person(){}

function Ninja(){}

Ninja.prototype = new Person();

// Allows for instanceof to work:

(new Ninja()) instanceof Person



What's challenging about this, though, is that all we really want is the benefits of 'instanceof', not the whole cost of instantiating a Person object and running its constructor. To counteract this we have a variable in our code, initializing, that is set to true whenever we want to instantiate a class with the sole purpose of using it for a prototype.



Thus when it comes time to actually construct the function we make sure that we're not in an initialization mode and run the init method accordingly:

if ( !initializing )

  this.init.apply(this, arguments);



What's especially important about this is that the init method could be running all sorts of costly startup code (connecting to a server, creating DOM elements, who knows) so circumventing this ends up working quite well.



Super Method



When you're doing inheritance, creating a class that inherits functionality from a super-class, a frequent desire is the ability to access a method that you've overridden. The final result, in this particular implementation, is a new temporary method (._super) which is only accessible from within a sub-classes' method, referencing the super-classes' associated method.



For example, if you wanted to call a super-classes' constructor you could do that with this technique.

var Person = Class.extend({

  init: function(isDancing){

    this.dancing = isDancing;

  }

});



var Ninja = Person.extend({

  init: function(){

          this._super( false );

  }

});
