title: Can regular JavaScript be converted to asm.js, or is it only to speed up statically-typed low-level languages?
body: <p>I have read the question <a href="https://stackoverflow.com/questions/14953351/how-to-test-and-develop-with-asm-js">How to test and develop with asm.js?</a>, and the accepted answer gives a link to <a href="http://kripken.github.com/mloc_emscripten_talk/#/" rel="noreferrer">http://kripken.github.com/mloc_emscripten_talk/#/</a>.</p>
  
  <p>The conclusion of that slide show is that "<em>Statically-typed languages and especially C/C++ can be compiled effectively to JavaScript</em>", so we can "<em>expect the speed of compiled C/C++ to get to just 2X slower than native code, or better, later this year</em>".</p>
  
  <p>But what about non-statically-typed languages, such as regular JavaScript itself? Can it be compiled to asm.js?</p>
