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
useEffecthook 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.
Navigation in React Native
- The
StackNavigatornavigator 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
useReducerhook in React Native is used for managing state with reducers, allowing for more complex state management compared to theuseStatehook, and providing a more predictable and debuggable state transition process.
