However the more beneficial question is how long does it take it to convert js-code -> bytecode and how much it boosts overall performance. Seems like it is very small compared to execution times. https://lists.webkit.org/pipermail/squirrelfish-dev/2009-May...
On the contrary V8 does the direct compile yet following jvm/jit techniques. More details by Lars Bak here http://channel9.msdn.com/Shows/Going+Deep/Expert-to-Expert-E... and here http://www.youtube.com/watch?v=hWhMKalEicY V8 does some more non traditional things like snapshotting, hidden classes, etc which give incremental performance boost. If there was a bytecode standard some V8 techniques might not be applicable but it is possible to maintain the performance boost.
I would love to see bytecode getting as a standard so that people prefer to stick to whatever language they are comfortable with. For instance I like both js and python but if there was an option, I would stick to python for all my needs.
Nitro follows lot of luajit methods and techniques some are outlined here by Mike Pall - http://article.gmane.org/gmane.comp.lang.lua.general/58908 Some adopted by Nitro - http://webkit.org/blog/189/announcing-squirrelfish/ Nitro does the js-code -> bytecode -> jit-optimization.
