At my current company, I occasionally have to step in and help with the front end (I'm mainly a backend guy) and we use Vue.js here. I'm hugely impressed every time I have to use it because of the amount of work that I can get done in such a short amount of time.

I probably sound like a fanboy, but every time I've used Vue.js, I've been astounded by how expressive it is.

All right, my daily fanboy quota has been filled.
