Python is kind of a special case. It's slow, widely used and often used as "glue" calling out to other programs and libraries that do the real work. There's also a lot of overlap for python and systems programmers, so there's tooling and that community knows how to do these things. There's more of a culture in python that to do anything serious (read fast) you write that part somewhere else and call into it.
If you look at JS tooling like eslint, tslint, uglifyjs, tsc, webpack, ~~esbuild~~, etc, it's all JavaScript (moving to typescript if anything).
EDIT: I stand corrected in that esbuild is not written in Javascript, but I think that's a disadvantage to it's success if anything and would point out webpack is more popular

Webpack exists since 2012, of course it's more popular. For a long time there were no other alternatives, so people had to deal with its madness.
