It outperforms Python at everything except where Python just calls a C function. Ruby (especially the recent releases) is on par with Python speed, if not faster. But neither is close to JS.

    Lol. Seriously though, show me a dynamic language (other than Lisp) that's even half as fast as Javascript...

      Without Python, Ruby, Javascript and Lisp, we are sort of running out of dinamic languages options.. But the funny thing is the one that got left out, is the one that is faster than Javascript: Lua

        Is it really faster than Javascript though? http://benchmarksgame.alioth.debian.org/u32/benchmark.php?test=all&lang=v8&lang2=lua&data=u32 http://benchmarksgame.alioth.debian.org/u32/benchmark.php?te...

        This is for the lua interpreter. aka the PUC-Lua You should compare it to Luajit, wich is a proper JIT compiler as V8.. The benchmark game used to have Luajit, but they take it out for no reason.. You can download the scripts and run in you local machine against V8, using Luajit for real comparison.. http://luajit.org/ http://luajit.org/ Also this link compare a lot of language implementations in different benchmarks than the ones in shootout http://attractivechaos.github.io/plb/ http://attractivechaos.github.io/plb/ edit: also see this blog post about benchmarks; if i am not mistaken, this guy is behind V8 and Dart VM's implementations http://mrale.ph/blog/2011/05/12/dangers-of-cross-language-benchmark-games.html http://mrale.ph/blog/2011/05/12/dangers-of-cross-language-be...
