Vue 3 - What's New? What Changed?

Views: 123 | Comments: 0   

Vue.js 3 is out! VueJS 2 already was an amazing framework, Vue 3 now improves it even more. It's mostly backwards compatible but there are a few changes you should be aware of. And there is one major new feature which is 100% optional but definitely worth a closer look!

I also updated my full Vue 2 course to Vue 3 (re-recorded it from the ground up!): https://acad.link/vuejs
