WinJS
open-in-new
<p>The Windows Library for JavaScript (abbreviated as WinJS) is an <a href="/facts/Open-source_software/HzTaB8E9">open-source</a> <a href="/facts/JavaScript/XhhIIEsl">JavaScript</a> <a href="/facts/Library_(computing)/xRzL3P7q">library</a> developed by <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a>. It has been designed with the primary goal of easing development of <a href="/facts/Windows_Store_app/PCIgnSjM">Windows Store apps</a> for <a href="/facts/Windows_8/eRtw96T3">Windows 8</a> and <a href="/facts/Windows_10/be9IHehJ">Windows 10</a>, as well as Windows Phone apps for <a href="/facts/Windows_Phone_8.1/X1NgxYPn">Windows Phone 8.1</a>, <a href="/facts/Windows_10_Mobile/JGjuL0fl">Windows 10 Mobile</a> and <a href="/facts/Xbox_One/Nom1XYbe">Xbox One</a> applications using <a href="/facts/HTML5/HBAxEAr6">HTML5</a> and <a href="/facts/JavaScript/XhhIIEsl">JavaScript</a>, as an alternative to using <a href="/facts/WinRT_XAML/SGUBJ4FJ">WinRT XAML</a> and <a href="/facts/C_Sharp_(programming_language)/UC2gxeyb">C#</a>, <a href="/facts/VB.NET/09mPEo4q">VB.NET</a> or <a href="/facts/C%252B%252B/Et0F2qn9">C++</a> (<a href="/facts/C%252B%252B%2fCX/qK3o57TW">CX</a>). </p><p>WinJS started as a technology that was specific to <a href="/facts/Windows_Store_app/PCIgnSjM">Windows Store apps</a>, but has evolved to aim at working in any <a href="/facts/Web_browser/2pfyymLs">Web browser</a>. In April 2014, during the <a href="/facts/Microsoft_Build/nVnk6tUD">Microsoft Build</a> developer conference, WinJS was released under the <a href="/facts/Apache_License/5AeIjas8">Apache License</a> as <a href="/facts/Free_and_open_source_software/1cHtjLCB">free and open source software</a> to port it to other than Microsoft platforms. A site dedicated to demonstrating the library has also been published. </p><p>Future development on WinJS is focused on maintaining what currently exists in the project. There are no plans for new features or feature requests, meaning no plans for a new feature release. However, the WinJS repository hasn't had a new commit since 2020. </p>
