initialize: function (arg1, arg2/ , arg3, ... , argn /) {
// This is the constructor function
// Properties added here will be private
this.privateArg = arg1;
},
const: { //Describes the constant members of your instances
const1: "Awesome, I'm immutable!";
},
private: { // Describes the properties that are only visible inside the instance
pv1: "only the instance methods can see me, sweet!",
secretFn: function () {
return "I'm invisible to the outside world.";
}
},
// All the other properties are public instance members
gimmeSecret: function () {
return "I'm a getter for a private member: " + this.secretFn();
}
});

var instance = testClass.new();

instance.const1; // => "Awesome, I'm immutable!"
instance.const1 = 'new value'; // throws TypeError

instance.privateArg; // => undefined
instance.pv1; // => undefined
instance.privateArg; // => undefined
instance.secretFn; // => undefined

instance.gimmeSecret(); // => "I'm a getter for a private member: I'm invisible to the outside world."
