We covered a lot of ground in this chapter. All applications created with the ArcGIS API for JavaScript require you to perform certain steps. These include defining references to the API and style sheet, loading modules, creating an initialization function, and so on. In the initialization function you will most likely create an instance of the Map class, add various layers, and perform other setup operations that need to be performed before the application is used. In this chapter you learned how to perform these tasks.
In addition, we examined the various types of layers that can be added to a map including tiled map service layers and dynamic map service layers. Tiled map service layers are pre-created and cached on the server and are most often used as basemaps in an application. Dynamic map service layers must be created on the fly each time a request is made and thus may take longer to generate. However, dynamic map service layers can be used to perform many types of operations...
