My point was that if you're comparing JS dependencies to other languages, you need to include their compilers too, since e.g. TypeScript projects depend on `tsc`. If you include the size of C/C++/Rust/Java/etc. compilers, I'm sure you'll find 50mb+ of dependencies. You're right that it's self-contained though (to be fair, so is `tsc` – most projects could shed a lot of dependencies by abandoning Babel in favor of `tsc` or esbuild).
