After installing through VS2015 > Tools > Extensions and Updates > Search (click and download and install from the web), I've been able to see and use the TreeView pane to navigate around .js and .html files with script tags.
BUT... I have several pages that use a custom script map that are seen by the VS editor as HTML pages, more precisely as Web Editor Forms. All the syntax is color highlighted correctly including the JavaScript code contained within the Githubissues.
Githubissues is a development platform for aggregating issues.
