To develop JavaScript apps for the Windows Store, you need to install Visual Studio Express 2012 for Windows 8 and Windows 8.
However, if all JavaScript templates are missing, try installing the following from the Microsoft website.
- "Update Microsoft Visual Studio 2013 5"; and
- "Visual Studio 2013 Extensions for the Windows Library for JavaScript"
After installing them, you may also be asked to install the "Tiered Hybrid Applications" from Visual Studio when you click on the JavaScript template.
