1 - Explain the React Native lifecycle methods.
ComponentDidMount: Called after a component is mounted and the DOM is rendered. Used for initializing state, fetching data, or setting up event listeners.
ComponentDidUpdate: Called when a component's props or state changes. Used for updating the UI or performing tasks based on the changes.
ComponentWillUnmount: Called when a component is about to be unmounted and removed from the DOM. Used for cleaning up resources, such as event listeners or timers.
2) What is the difference between props and state in React Native?
Props: Immutable properties passed from a parent component to a child component. They cannot be modified by the child component.
State: Mutable properties that are managed by the component itself. They can be updated using the `setState` method.
3) What is the purpose of the `render` method in React Native?
The `render` method returns the UI for the component. It determines what is displayed on the screen.
4) How do you handle asynchronous operations in React Native?
Using promises, async/await, or third party libraries such as Redux Saga or Redux Thunk.
5) What are the different types of navigators in React Native?
Stack navigator: Navigates between screens in a stack, allowing for back and forward navigation.
Tab navigator: Allows for switching between tabs at the bottom of the screen.
Drawer navigator: Presents a drawer that can be opened from the side of the screen.
6) How do you style components in React Native?
Using JavaScript stylesheets (JSX), inline styles, or third party libraries such as styled components or Material UI.
7) What is the purpose of the `useContext` hook in React Native?
Provides access to context data from the parent component without having to pass it through props.
8) How do you handle deep linking in React Native?
Using the `Linking` module to listen for deep link events and navigate accordingly.
9) What are the best practices for handling state management in React Native?
Using a state management library such as Redux or MobX.
10) How do you optimize performance in React Native apps?
Using the `PureComponent` class, memoization, and avoiding unnecessary re renders.
