Mootools var Cat = new Class({ initialize: function(name){ this.name = name; } }); Prototype var Cat = Class.create({ initialize: function(name){ this.name = name; } }); Dojo var Cat = dojo.declare(null, { constructor: function(name){ this.name = name; } }); YUI var Cat = Y.Base.create('cat', null, [], { initializer: function(name){ this.name = name; } });
