I would like to thank Packt Publishing for seeking and asking me to be part of this exciting book. I hope that the body of knowledge stored in this book will be a great asset to those who want to learn how they can leverage programming for GIS. I would also like to extend a warm thank you to Guillermo Paniagua, a colleague of mine, for his input and insight on GIS topics in this book, which helped me review this book. The endeavor to continually learn cannot be a solo activity, and the best results always come from team work and peer review.

Web technologies are changing rapidly and so is the ArcGIS JavaScript API. Regardless of your development experience, ArcGIS offers an easy way to create and manage geospatial applications. It gives you access to mapping and visualization, analysis, 3D, data management, and support for real time data.
