In this talk from YUIConf 2011, Jeff Burtoft (@boyofgreen), Lead Frontend Engineer at USAA, shares what he’s learned about building performant and scalable cross-platform mobile web apps using YUI. In the course of the talk, Jeff reveals some of the pitfalls of dealing with device limitations — particularly when building native-wrapped web apps that run in web views — and explains how he and his team worked around them using YUI.
