I agree you can avoid it with care, but I do think it's a JavaScript problem, at least moreso than in other languages. The culture is one of acceptance of churn. It seems like everything from minor libraries to major frameworks is much more likely to introduce a breaking change in JS than in Rust, C++, or even python. I've never written any emacs lisp that I had to change when upgrading emacs, and the third-party libraries I use there also tend to deprecate things rarely and carefully. But, if we stop working on a JS codebase for more than a few months, there's a very real chance that it will no longer build with current tools or that an upgrade to fix e.g. a security vulnerability will turn into a gordian nightmare.
