DESCRIPTION
Ext JS 4 has a thoroughly revamped architecture that enables faster performance and more developer flexibility. In this session, we will take a tour through the revamped architecture of Ext JS 4.x, taking a high-level look at the updated data package, component hierarchy and core APIs. Afterwards, developers will have an understanding of why Ext JS 4 works the way it does and how best to leverage its underlying APIs.
