this comparison doesn't really make sense since JS as a language keeps a lot of old baggage to maintain backwards compatibility.

In reality it makes little difference whether source code needs to be fixed because of a breaking language or dependency update. Even in C/C++ I need to go over my code whenever I update to a new compiler version because of new warnings.

And that is why when no one pays the budget for doing tooling upgrades in big corps, the tooling never gets updated.
