1 - Explain the architecture of React Native.
React Native uses a bridge to communicate between the JavaScript code and the native platform code.
The JavaScript code runs in a separate thread, while the native platform code runs on the main thread.
This architecture allows React Native to achieve high performance, as the JavaScript code does not block the native platform code from running.
2) Describe the difference between a state and a prop in React Native.
A state is a local data store for a component that can be modified by the component itself.
A prop is a data that is passed from a parent component to a child component.
Props are immutable, while state can be changed.
3) How do you handle navigation in React Native?
React Native provides the `react navigation` library for handling navigation.
This library allows you to create different types of navigators, such as stack navigators, tab navigators, and drawer navigators.
You can use the `navigate()` method to navigate to a new screen, and the `goBack()` method to go back to the previous screen.
4) How do you handle data fetching in React Native?
React Native provides the `fetch()` API for making HTTP requests.
You can use this API to fetch data from a remote server, and then use the `setState()` method to update the state of your component with the fetched data.
5) How do you optimize the performance of a React Native app?
There are a number of techniques you can use to optimize the performance of a React Native app, such as:
Using the `pureComponent` method to avoid unnecessary re renders.
Using the `memo` function to avoid unnecessary function calls.
Using the `ShouldComponentUpdate` method to control when a component should re render.
Using the `Animated` API to animate components efficiently.
