State management is a process of managing an application’s data. As a developer, it is important to ensure data remains consistent and synchronized across different application parts.

You’ll start by learning the state management strategies in React Native using state and props and create a real-world Funbook application using only React Native built-in solutions. You’ll learn about the Redux and MobX libraries and how these can be used to implement the like button in the app. Next, you will implement the like button using the XState library that treats the state as a finite state machine. You’ll also learn about the Jotai library that uses atomic state for state management. Finally, you’ll learn how React Query offers comfortable fetching and data mutation on the server that replaces global state management needs.

After completing this course, you will be equipped to implement complex state management functionalities, ensuring data consistency and synchronization across different application parts.

State can be changed within the component, while props are read-only.

State is a representation of the current state of the application, while props are read-only.

State is internally managed and controlled within a component whereas props are external inputs passed to a component.
