Study Notes

React Native Concepts

The bridge module in React Native serves as a liaison between native modules and JavaScript modules, allowing them to communicate seamlessly.

Hooks in Functional Components

The useEffect hook is used for handling side effects in functional components in React Native, enabling the execution of functions after rendering or updating components.

State Management

Redux is a state management library used in React Native development to manage global state by providing a single source of truth, making it easier to debug and scale applications.

The StackNavigator navigator in React Native is used for creating stack-based navigation, allowing users to navigate between screens using a last-in, first-out (LIFO) principle.

State Management Hooks

The useReducer hook in React Native is used for managing state with reducers, allowing for more complex state management compared to the useState hook, and providing a more predictable and debuggable state transition process.
