Quite true, I also prefer Vanilla JS and look forward to Web Components becoming more mainstream.

The pure Web stack skills stay, while framework specific skills are only good until the next JS Framework hype cycle.

Where are Dojo, MooTools, YUI, Promise.js now?

In a couple of years React, Angular, Vue, Polymer might join them, but VanilaJS, HTML, CSS skills will stay relevant.
