MobX is a battle tested library that makes state management simple and scalable by transparently applying functional reactive programming. React and MobX together are a powerful combination. React renders the application state by providing mechanisms to translate it into a tree of renderable components. MobX provides the mechanism to store and update the application state that React then uses.
Let's explore the basic differences between Redux and MobX, then dive into some real-world examples of how to use MobX in your React application.
