Sure, but when was the last time you saw, say, a Python project using some third-party library instead of simply calling isnumeric() from the standard library?
There's a reason for these jokes always being about Javascript.
I don't think typescript exists because JavaScript wasn't designed to be statically typed. I think Typescript exists because JavaScript wasn't really designed, period.
Must be pretty good, considering literally every time I check in on the JavaScript community it is somehow more on fire than it was last time. I guess I must have a front row seat to all their misfortune. Either that or they're just incompetent, but it couldn't be that, could it?
