The problem with generics type erasure is less of an issue though in practice because the ecosystem is generally compiled from typed code and hence the compile-time guarantees reduce the dangers of erasure. This is unfortunately not true in TypeScript where you encounter plain JS all the time (sometimes TypeScript wrappers of dubious quality) causing more havoc. So while _theoretically_ type erasure could be considered having similar problems, in _practice_ it is much more manageable in Java. I guess if the whole JS ecosystem would be TypeScript only it would be less of an issue there as well, but right now it can be messy.
