State management without pain
summary
Claims that MobX observables make state management simpler than Redux by deriving values automatically and updating only when needed, demonstrated with React components using computed values and reactions, transactions in actions that batch updates, helpers like toJS and RxJS adapters, devtools and trace for debugging, and a practical counter built with MobX-State-Tree runtime type checking and lifecycle hooks (afterCreate interval). Notes that MST adds overhead and becomes slower when mutating arrays of thousands of objects.
