What is your favourite JS library for the UI front-end?

and decided to use vue because it is very easy to use and well documented. Really enjoying it so far.

Yesterday, I experimented little bit with Vue.js, still learning the basics. Would be nice if you give your opinion on my other question at:

Phoenix with: a JSON API and Vue.js, or, HTML (eex) with partial use of Vue?

I hope you can help me choose between two possible setups: a. Phoenix JSON API on the back-end and Vue.js on the front end to render views / lists / filters / forms (basically all UI). b. Phoenix HTML views (eex) and partial use of Vue.js on the UI for special elements (such as nested forms). Which solution gives better overall user performance experience?

Thank you.
