I say this out of genuine surprise, not judgment -- I never would have guessed that native Typescript is significantly faster than native Python. To be fair, I don't know if "significantly" is justified. I get that Typescript is typed (heh) and Python is not, but compared to my daily driver language (also not typed) Python is so much faster that I subconsciously think of typing as not being the major performance unlock. But I guess once you optimize the rest, typing is (nearly) the final boss of performance.
