Sharing the business logic makes sense, but I'm not confident that sharing code on web and mobile devices is a good point in terms of performance.

The UI in JS is simple to develop, but you have a lack of performance also

From my experience with servers-side JS code, if your JS is fast enough to run with every server request, it's also fast enough to run on today's mobile processors. Obviously for Client-side code this isn't true, but then again if you want your apps accessible from mobile browsers, you need to have it reasonably optimized anyway.
