Over the course of this chapter, we have learned about many of the features offered by the Dojo framework, which is packaged with the ArcGIS API for JavaScript. We've learned about the three major packages in Dojo, and how to use them to create applications. We learned how to create our own modules, and we modified an existing application to make a module that could be imported into any application.
In the next chapter, we will learn how the ArcGIS API for JavaScript communicates with ArcGIS Server through REST services.
