In this chapter, we've developed an Ext JS extension, a fancy animated message bar. Throughout this chapter we've learned how easily we can create our own customized control. As we've already learned about the power of Ext JS extension and how easily we can create Ext JS extensions, we can see that it is really easy to create our own control, which helps to fulfill our custom requirements.
