Favourite JavaScript Framework?

Vue for sure! light, clean and powerful. You can do a lot of stuffs with it.

Angular for sure, but I am may be biased

React.js is really good, one of the best I have tried

I've to go w/ React. Has a huge community and you can create both simple PoC projects or more robust ones w/ it.

My favorite is VueJS, every time i using this.

React.js & Angular use currently a lead

I've used a lot: ember, react, vue, angular, etc etc etc. I do most of my daily work in React, however.

I really like Vue.js for professional purpose.
But I do enjoy Svelte too !
