Started by looking at an imba talk* and then went over to scrimba and it surprised me how you can pause and live edit the code during the presentation, really impressive feature.

Imba seems cool and familiar coming from Vue.js, but learning new language is quite a step. Also I like templates more separated from component's code. But memoized dom and mutation based state management are great features. Missing server-side rendering though.
