WinJS is an open-source JavaScript library that can assist you in building HTML, CSS, and JavaScript applications for the Windows Store with a consistent look and performance across all Windows devices. WinJS will work in any browser and can be used as a standalone solution or with other frameworks and libraries.
WinJS makes it possible to add Windows UI controls in HTML, such as ListView, FlipView, and Semantic Zoom, features like virtualizing collections, and high-quality infrastructure like page controls, promises, data-binding, and a template engine.
Use WinJS not only for your Universal Windows apps with HTML/JS, but also for your websites, and when using HTML-based app technologies like Apache Cordova. The library consists of modules that bring JavaScript coding conventions to Windows Runtime functionality.
