WinJS

WinJS provides helpers that facilitate the development of Windows Store apps using HTML5 and JavaScript. The library consists of modules and functions that expose the Windows Runtime in a way that is consistent with JavaScript coding conventions. WinJS makes it possible to add Windows UI controls in HTML. This is accompanied by support for data binding and a template engine.

Other JavaScript frameworks, such as JQuery, can work side-by-side with WinJS. The library comes with additional declaration files for a rich developer experience using TypeScript, a strict superset of JavaScript with annotations. TypeScript enables for code completion and refactoring while maintaining compatibility with JavaScript.

• UI controls with fundamental support for touch, mouse and keyboard.
• Scaffolding.
