An Example Class

gistfile1.js

function User( options ) {
  (this.options = options || {} ).__proto__ = User.options
  
  // Private
  function utilityMethod() { return "oh hai" }

  // Public
  this.say = function say() {
    return this.options.awesome ? utilityMethod() : ':('
  }
}

// Default options
User.options =
  { awesome: false
  , role: 'staff'
  }

// Instance
var karbassi = new User({ awesome: true })
karbassi.say() // "oh hai"

You're missing a semi-colon ;)
