It's baffling to me how distant of a second it is in terms of popularity. Instead of forcing you to contort your program into a special paradigm in order to deal with reactivity in a sane way, it simply makes reactivity a non-concern (while remaining pretty simple and predictable when you do actually care to dig beneath the magic). You can write code in a way that's natural and simply not think about reactivity most of the time, and you'll even get better performance in many cases because of the highly-granular pub/sub that it sets up automatically. I cannot praise this paradigm enough.

And then there's Vue.js which essentially has MobX functionality built in. When you want to update the state, you just...update the state, which can be a plain JS object that knows nothing about the front-end framework. I've used it for several medium-size projects and haven't gotten close to needing anything like Redux or Vuex.

Yeah, although when I played with Vue a couple years ago it seemed like it wasn't quite as powerful as MobX (particularly when you start stacking up a graph of computed values, or when you want to create side-effects of your own). But definitely a similar idea.

I was a fan of MobX+React until I to a look a Vue when version 3 came out. Now I'm a Vue fan and what I was doing before feels like overkill.
