I accidentally wrote a (bad) version of MobX's core mechanism before I learned about it. At its heart it just uses object Proxies to intercept getters and setters; the former to find out where something is used, the latter to find out when it changes.
It can feel a bit magical sometimes, but the magic isn't hard to understand, almost always just works, and when it doesn't do what you want it usually causes a performance impact, not breakage.

I don't know what you mean. Aside from "tracking" which observables get accessed within it, all it does is decide when to trigger updates.
