The python community gaslighting the js community.
As a Python developer, I am absolutely giving ya'all a hard time for your gross bolted-on JavaScript type solution. /s
I do this primarily because I find it cathartic while I work with our gross bolted-on Python type solution. /s (mostly sarcasm, some truth here)
I do this secondarily because I'm jealous that Typescript seems to be a good bit more mature than MyPy. (No sarcasm here. I really am jealous on this point.)
