  Under the section "The Property (object attribute)" the code segment has two curious lines. I expect the first cancels out the latter, making the latter useless.

       // in Person function
       this.gender = gender;
       // outer scope (gender will never be this value because it is overridden by the person constructor argument)
       Person.prototype.gender = 'Person Gender';
  

  Am I correct, or does the prototype.gender line have some other purpose than instantiating gender to a value that is immediately overridden by the passed in value (or undefined if no value is passed)?

  Might want to check the Joose object system (http://joose.it/ #joose on irc.freenode.net), highly inspired in the awesome thing that Moose (http://search.cpan.org/dist/Moose/) is to Perl. There's even a port of KiokuDB as KiokuJS!(http://joose.it/blog/2011/01/13/introducing-kiokujs/) :)

  It's good to know this stuff, but in my real-world usage of JavaScript, I've become a big fan of Backbone.js to help structure code intelligently, etc.

  > Inheritance A Class can inherit characteristics from another Class.

  Somebody should tell Mozilla, that there are no classes in JavaScript....

  I really like Mozilla's docs. I read this one recently actually.
