Indeed comparing with CPython, which the link is about. Indeed CPython is not JIT and PyPy is, but CPython is unfortunately usually what you get, comparing with PyPy would not be fairer since the goal is to speed up "vanilla" CPython. It's unfortunate to me that the default python interpreter, so widely used for scientific computational purposes, is so much slower than the JS interpreter you get in your web browser, and then we're being happy +24% benchmark results about this when 30x faster is known to be possible (e.g. with JIT).

Just checked and pypy has the same speed as JS (instant). You are right that this is not what the most people use when working with Python and there is package incompatibility. I am curious but don't have the time to check would the same result be for a regex?

  I didn't check myself, but in the link from the other comment regex is the one thing where python wins! https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/python.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... Of course this is testing two native implementations of regex parsing, not the higher level scripting language handling.

Right but there's no "standard" JavaScript engine either. Benchmarking V8 against CPython and pointing out a totally expected 30x speed difference isn't insightful

  I still have to disagree, it's not because both slow and fast JS engines exist (recent ones vs those from before around 2008), or both slow and fast python engines exist (CPython vs PyPy), that it's not ok to point out that the vanilla official python interpreter is much slower than possible. Why does one have to be ok with a totally expected speed difference? This is the official interpreter of a language, they give a slow tool by default, the official tool deserves scrutiny.
