Why You Shouldn't Write OO

The document discusses why object-oriented jQuery code should be avoided. It recommends using an event-driven approach instead, where components trigger events to communicate rather than calling methods directly. This fits more cleanly with asynchronous requirements and how users typically interact with elements like autocompleters. The document provides an example of building tab functionality in an event-driven way by binding to click and keypress events that trigger a tabactivate event.
