Vue with Wordpress

Can I use Vue JS with wordpress plugin and not jQuery?

I believe you can

Yes you can.

I am still not confirmed … there must be someone from #authoring-on-envato:hangouts or review team who can help us to confirm that whether we can use Vuejs in themes. @ThemeBeans @emiluzelac @kailoon

eventhough you can
i personally don’t recommend
because many people may not like SPA for wordpress especially because of SEO reasons.
2. definitely you end up using jquery as most of the plugins rely on it.
