Vue.js is relatively new framework. It’s mostly an ergonomic and on-boarding improvement over other frameworks. It borrowed something from everything but hasn’t yet introduced anything new. This might change as we collectively move toward Progressive Web Apps. I also heard that NativeScript will soon support Vue.js.
It’s a great framework, but I’m not yet convinced that it should be used for the kinds of projects that Angular, Ember, React and Polymer are being used for.
