🔗 The Inverted reactivity model of React

In the r/vuejs sub, there are occasionally questions from React devs wondering how to prepare for a transition to Vue (rare, but it happens! More often, it's going the other way; this topic is important both ways!).

While there are obviously a great many differences syntactically, I actually think that one of the most important things for React developers to understand about Vue -- and almost every other reactivity model, including Vanilla JS as well -- is that React's model of reactivity is actually "inverted".
