MobX State Management

MobX is a state management library built on reactive programming principles. Instead of Redux's action-dispatch-reducer loop, MobX uses observables—variables that automatically notify subscribers when changed. When observable state changes, MobX notifies all dependent computations and React components, triggering efficient re-renders. It's minimalist: you write normal mutation code inside @action methods, and MobX handles the rest. MobX enables a "fine-grained reactivity" model where each component subscribes only to the state it uses, avoiding unnecessary re-renders. This is especially powerful for complex forms, real-time dashboards, and collaborative apps where state changes frequently.
