The document summarizes the goals and key features of the new Yahoo! homepage and YUI 3.0 library. YUI 3.0 aimed to eliminate global dependencies, reduce file sizes for faster loading, create version independence between releases, and allow code portability. It achieved these goals by removing the YAHOO global namespace and modularizing the library into smaller independent modules to improve performance and flexibility.

Editor's Notes
- Over the past couple of years, we've seen JavaScript development earn recognition as a true discipline. The idea that you should architect your code, use patterns and good programming practices has really elevated the role of the front end engineer. In my opinion, part of this elevation has been the adoption of what has traditionally been considered back end methodologies. We now focus on performance and algorithms, there's unit testing for JavaScript, and so much more. One of the areas that I've seen a much slower than adoption that I'd like is in the area of error handling. How many people have an error handling strategy for their backend? How many have dashboards that display problems with uptime and performance? How many have anything similar for the front end? Typically, the front end has been this black hole of information. You may get a few customer reports here and there, but you have no information about what's going on, how often it's occurring, or how many people have been affected.
