Oh if only mentioning mithrils name would be enough to explain it's benefit I think a lot more people would be using it, but we need to do a bit better than that. Mithril is one of the few libraries that really embraces JavaScript and the beauty of a clean abstraction and lean API. There's no heavy learning curve, just learn a couple of method signatures, and you're ready to go. Once you need to do something advanced or use a third party library mithril won't be in your way! I still haven't seen anyone happily go back to react or vue for that matter after experiencing mithril.
