Yes, I understand those are frameworks not languages. The point was that since TIOBE indexes against the word 'javascript' and not 'node,' etc. I think it's possible that JavaScript's relative usage is obscured.

This is purely anecdotal on my part but it seem to me I see many posts or articles talking about 'writing an app in node.js' or 'the UI was written in jQuery' rather than 'written in JavaScript.' This seems to me a phenomena more or less unique to JavaScript.
