That's not an objective comparison, since Javascript has been optimized to deal with arrays and numbers, as that's one main use-case that people have in the browser. Take a look at the source code and tell me if that's the kind of code that you write.

What were your thoughts on the regex-dna benchmark?

V8 is able to compile PCREs directly into efficient machine code (in some cases at least), CPython is not.

Thanks for the insight!

So it's not an objective comparison because the V8 implementation performs well? :-)

No, it's not an objective comparison because that's not the kind of code that we deal with in 90% of the cases, except when doing games, but then again plain Javascript is shitty for doing games, unless you develop in a strict subset that isn't meant for humans.

Even if it were "not the kind of code that you deal with in 90% of the cases" that would not mean it "was not an objective comparison".

It might mean it wasn't a relevant comparison for you; but if those 10% of cases were performance critical it would be very relevant.
