In this chapter, we have covered the basics of what you need to do to get Ext up and running, and what a simple script looks like. It's easy to miss a minor detail and get stuck with an error message that makes no sense. But now, you should be prepared to conquer any initial errors that you might come across.
The example we created showcases what Ext excels at: providing the user interface. We only used dialogs, but, as you now know, a few lines of code are all that are needed to display an Ext widget. The main goal of this chapter was to get Ext installed and working, so we can start creating some really sweet widgets.
