With JIT compilation, asm.js, tracing, it is hard to argue against. A long fought browser war really brought out the maximum capabilities of the JavaScript engine. http://en.wikipedia.org/wiki/JavaScript_engine#Performance_evolution http://en.wikipedia.org/wiki/JavaScript_engine#Performance_e... asm.js promises speed 2x slower than native code. For interpreted code, that is amazing.

None of those are interpreters. You're trying to compare Javascript against other JITted / compiled languages. Mozilla themselves claim that asm.js is only about 2x slower than C.
