1.7. Summary

In this introduction to Ext JS, you learned how it can be used to build robust web applications or integrated into existing websites. You also learned how it measures up against other popular frameworks on the market and that it’s the only UI-based framework to contain UI-centric support classes such as the Component, Container, and Layout models. Remember that Ext JS can ride on top of jQuery, Prototype, and YUI.

We explored many of the core UI widgets that the framework provides and showed that the number of prebuilt widgets helps rapid application development efforts. In doing that, we talked about some of the changes that Ext JS 3.0 has brought forth, such as Flash charts.
