ESRI Javascript API

I have only recently begun to delve into these lightweight web mapping APIs of which the ESRI Javascript API is the first.  I have also completed my first dijit/widget which is an encapsulation of the ESRI LayerSwipe dijit into a custom interface. All of the widgets on this page can be tested by clicking the city map link below.
