A very welcome feature embedded in the new JavaScript Windows Metro style app templates in the Visual Studio 11 beta is that they accommodate built-in support for databinding, using sample data in a JSON array.

G. Andrew Duthie in this blog titled “Databinding in Windows 8 JavaScript Metro style Apps” introduces you to databinding in Windows 8 JavaScript Metro style apps. This Microsoft Developer Evangelist in this article covers the basics of the databinding implementation.
It is easy and straightforward, and having a template that provides a clear implementation with sample data can help you get started with your own application.
