2 things for me: 1) 2-way bindings. i used to hate the concept of it as it was a form of black magic and had hard to debug performance issues ala Angular. but in Vue, it is actually fast and straightforward, it's essentially a light boilerplate around getter/setter methods. it took me a while to convert to this way of thinking but once i did, i never looked back. 2) @click, @submit, @emit, :some_property. at first glance, those unconventional symbols/etc irked me and was turned off by it. but after 5 min reading their doc, it became really intuitive and extremely handy. its unlike Angular who have way too many things going on, with Vue its minimal.
