I am going to present a solution that combines the best of native and multi-platform app development - a slick and responsive native UI and shared application logic with no compromise on performance. It is important on multiple levels: -it can save development time since the bulk of the application logic is shared and implemented only once; -it doesn't compromise a native performance since there is no bridging between the target platforms and the shared code; - it solves the problem of diverging implementation of the same logic on different platforms.
