JavaScript in WT allows programmers to build apps using HTML and CSS. A lot of WT apps using JavaScript are as same as writing markups for the website. In addition to this, JavaScript on WT provides some additional features and introduces some different ways that you can use it under this platform. Since the implementation of JavaScript varies from platform to platform in WT, it's more or less in the Microsoft style where, with default JS properties available, WT adds some extra features for JavaScript. This provides the enhanced support of touch, more control over the look and feel of the UI (user interface). This also provides controls such as DatePicker, TimePicker, and ListView, and an exclusive access to WinJS.
