No, I do not say that. I say that Vue is not able to handle any third part library that uses arrays and are not ready for Vue. But even worst, Vue blames JavaScript for their poor choosing of state update strategy. I have seen lots of companies starting with Vue, and then, after a few months, getting rid of it, because of this design flaw.

I really do not care about this flaw, I like to use Redux, or Vuex, and it works in Vue perfectly. So that limitations is not really a problem for me. The problem is blaming JavaScript for its own design flaw.
