> iOS and Android are successful because they offer a great selection of powerful APIs, not because of the particular binary representation they use for applications.
They also provide great battery life and user-visible performance (iOS especially), have incredibly well integrated development tools (see Apple's Instruments and its power, CPU, syscall, et al profiling), and give software authors the escape hatches they need to maximize performance when absolutely necessary.
It's not just a question of nice APIs. Layering another level of JavaScript spit and bubblegum on top of the problem is t going to make any of the above easier.
