YAHOO Global Object: Examples

• User Agent Detection: YAHOO.env.ua can tell you with some accuracy which browser your page is being viewed in.
• Creating Class Hierarchies with YAHOO.lang.extend: Leverage class inheritance in an object-oriented architecture.
• Creating a Composition-Based Class Structure Using YAHOO.lang.augmentProto: Use YAHOO.lang.augmentProto to help modularize class behaviors.
• Add Behavior to Objects or Static Classes with YAHOO.lang.augmentObject: Use augmentObject to extend static classes, object literals, or class instances.
• Combining Simple Data Sets with YAHOO.lang.merge: Merge several objects, creating a unique set.
