Using the Yahoo Global Object to Manage Object Inheritance and Composition: Four New YUI Examples

• Creating Class Hierarchies with YAHOO.lang.extend — explores the use of YAHOO.lang.extend to build traditional class-style hierarchies in JavaScript;
• Creating a Composition-Based Class Structure Using YAHOO.lang.augmentProto — as Luke puts it, "the intent of augmentProto is to aid in extracting nonessential behaviors or behaviors shared by many classes, allowing for a composition-style class architecture"; in this example, he shows you how to do that by applying the YUI Event Utility’s EventProvider functionality using augmentProto;
• Add Behavior to Objects or Static Classes with YAHOO.lang.augmentObject — augmentObject provides functionality similar to that of augmentProto, but is designed for work with static classes where you want to confine your augmentation to the target object (rather than its prototype);
• Combining Simple Data Sets with YAHOO.lang.merge — in a different category, YAHOO.lang.merge allows you to combine two objects together, outputting a third (new) object.
