Vue.js 2
vuejs.orgThe benchmarks[1] make me intrigued, along with the perceived ease of use. It seems well maintained as well, but I think that Angular or React will get a bunch of these improvements, given the sheer amount of contributors they have, and that they are backed by large companies.
The blog post[1] in general is quite intriguing, recommend giving it a read.
