I have the script...

```
 var MyClass = {
        someText: 'Hello World'
    };

    jQuery(document).ready(function () {

        console.log(MyClass.someText);
        MyClass.prototype.someText = 'proto Hello World';
        console.log(MyClass.someText);

    });

```

But I get an exception saying...

```
Microsoft JScript runtime error: `MyClass.prototype is null or not an object`

```

But when I read about the prototype it says its avaiable to all instances of an object but the above seems to disprove this. Whagwan?
