[Proto-Scripty] what is the advantage to use Class.create to create new class

[maven apache]

Hi:

I am using prototype1.4 now.

When create new class using prototype ,people used to use this manner:

var Person = Class.create();
Person.prototype = {
   initialize: function(name) {
     this.name = name;
   }
   printName: function() {
     alert(this.name);
   }
}

However I can not see the advantage of this manner,since it is very readable
when use the native javascript:

function Person(name) {
    this.name = name;
}
Person.prototype = {
    printName: function() {
        alert(this.name);
    }
}

Anyone can tell me why?
