WinJS embraces common open source development tools (like Grunt, LESS and QUnit), and is intended to be a collaborative process that allows developers’ contributions. You can check out and comment on a clear roadmap that’s been published on the GitHub site.
We are also happy to share that WinJS is also coming to Windows Phone 8.1 and Xbox One. That means that developers can deliver the same advanced, polished and modern user experience to a variety of browsers, including Chrome and Firefox, and to a variety of devices, including Windows, Windows Phone, Xbox One, iOS and Android.
You can take WinJS code for a spin by visiting the “Try WinJS” site.
The engineering team working for MS Open Tech on WinJS has published additional information about the project on a blog post.
You should also check out the buildwinjs.com for more detailed information about the WinJS feature set, the WinJS Wiki page to learn about the roadmap, the “Try WinJS” site to play with the code and the GitHub page to get your hands on the code.
We can’t wait to see what you do with WinJS and look forward to hearing from you about how you plan to use it across Chrome, Firefox, IE, Windows, Windows Phone, iOS, Android…
