As you pointed out yourself, JavaScript is a poorly designed mess. It may be a "high level" language, but it's also dangerous to use. None of the linters do a perfect job of ferreting out all the problems. In other words, JavaScript will never be 100 per cent "safe" to use. Treating it as a lower level of abstraction doesn't harm us. It simply gives us a foundation for using better languages, and that has to be a Good Thing.
