How is state stored in React? What state managers have you worked with?

In React, component state is usually stored using the useState hook for local state or useReducer for more complex logic. For global state, state managers are often used.

I have worked with the following state managers:

• Redux — a classic and popular manager that uses a centralized store and the Flux pattern.
• MobX — a more reactive and less pattern-based approach with automatic change tracking.
• Context API — a built-in React mechanism for passing state through the component tree without props.

For example, with Redux, the state is stored in a single store object, and changes occur through dispatching actions, which makes it easy to track and debug the application's state.
