Did you? :-)

That Node pidigits program also uses GMP.

Besides those 2, did you notice other JS programs not 50x faster than the corresponding Python programs ?

There are 2 programs there that are 50x faster in JS, other 40x, other 35x, other 16x, a couple 7x, not sure what are you arguing about.

The importance of looking at more than one measurement.

I never made the assertion JS is 50x faster...

But everyone knows it is significantly faster than Python. Probably at least a few times for pure JS vs. pure Python programs. Not that it matters, Python is basically glue to run mostly C and C++ programs.

Given that you say "basically glue" why the previous surprise about "basically using C types and GMP" ?

Because it's obviously not the idiomatic way to use Python. No one is going to bother writing a program that way in Python, they'd just write it in C or C++ then link it.

Sorry, I gave up thinking I knew what people would or wouldn't bother doing a long time ago.
