What is State Management?

In React Native, a state is an object that stores data related to a component. Whenever the state changes, the component is rerendered. Hence, the state controls the behavior and rendering of components in React Native. It plays a crucial role in displaying information dynamically to the users. For example, the state can store data related to the themes of an application. Different users can be shown different themes depending on their preferences. We have to manage and maintain multiple such states inside applications. This is known as state management.
