Compile is rather generous. The massive teetering dependency tree certainly is prone to breaking, but I am not certain I can draw much parallel between the API stability of JS vs the ABI stability of libcurl. If anything, I can still properly render some pretty dang old websites just fine and, for the most part, the websites will work just fine. Mainly benefitted by the light use of JavaScript using probably no external dependent libraries. Though your milage will vary depending on if you go back to browser specific APIs when all that browser war nonsense was going on. I love to bash on JS as much as the next guy, but a large portion of the blame is actually the modern use of it, not an inherent quality of the language breaking compatibility over time.
