Udemy Vue JS 2 — The Complete Guide (incl. Vuex)(this is paid course unfortunately and I have not tried this course).
Vue.js 2 learning resources note

I’ve bought it with a discount for ~$20 and currently almost completed it — very involving, includes couple projects which You can try solve alone or with the teacher — I would very recommend this course for anyone! (Personally, I haven’t tried Vue 1.x, but after this course Vue 2 is no magic for me ;) )
