New geocoder widget
Add a geographic search box to your app with a couple of lines of code. The widget defaults to the ArcGIS Online World Geocoding Service but can be customized to use one or more ArcGIS Server geocoding services.
New map constructor options
The map class has new constructor options that can help you get your map set up using less code.
basemap: ArcGIS.com basemap, such as “streets”, “satellite”, “osm”, etc.
center: Array of two coordinates (longitude, latitude) or an esri.geometry.Point.
zoom: Starting zoom level for the map.
minZoom: Smallest scale zoom level for the map.
maxZoom: Largest scale zoom level for the map.
The map now auto-resizes so it is no longer necessary to set up an event listener for resize events on the map’s container to call map.resize when a map’s container resizes.
Below is a comparision of pre-3.3 code and equivalent 3.3 code.
