1 - Explain the Flux architecture: Flux is a unidirectional data flow architecture used in React Native to manage application state. It helps maintain a single source of truth and simplifies debugging.
2) Describe the difference between props and state: Props are immutable values passed down from parent components, while state is mutable data that can be modified within a component.
3) Explain the significance of the render method: The render method in React Native is responsible for defining the appearance of a component based on its props and state. It should be pure, only returning the UI elements to be rendered.
4) Discuss the lifecycle methods in React Native: Lifecycle methods are hooks that allow developers to respond to events such as component mounting, updating, and unmounting.
5) Explain the use of navigation in React Native: Navigation allows users to navigate between different screens in an app. Common navigation libraries used in React Native include React Navigation and react router native.
6) Describe the difference between a class component and a function component: Class components use the ES6 class syntax and have a lifecycle method and state, while function components use the ES6 function syntax and only have access to props.
7) Explain the use of Redux in React Native: Redux is a state management library that helps centralize application state and simplifies data flow.
8) Discuss the principles of cross platform development in React Native: React Native allows developers to build apps for both iOS and Android using a single codebase, ensuring consistency across platforms.
9) Explain the use of Expo in React Native: Expo is a framework that provides pre built tools and libraries to simplify React Native development, such as over the air updates and push notifications.
10) Describe the use of Jest and Enzyme for testing React Native apps: Jest is a testing framework used for writing unit tests, while Enzyme is a library used for writing integration tests in React Native.
11 - Discuss the benefits of using React Native over native development: React Native combines the benefits of cross platform development with the efficiency and power of React, reducing development time and costs.
12) Explain the use of React Native Elements: React Native Elements is a UI library that provides a set of pre built components, such as buttons, inputs, and lists, to simplify app development.
13) Describe the significance of performance optimization in React Native apps: Performance optimization is crucial in React Native to ensure a smooth and responsive user experience. Techniques include using immutable data structures, avoiding unnecessary re renders, and optimizing network requests.
14) Discuss the role of the React Native CLI: The React Native CLI (Command Line Interface) provides commands to create, build, and run React Native projects, simplifying the development process.
15) Explain the use of React Native Hooks: React Native Hooks are introduced in version 16.8 to simplify state management and reduce boilerplate code, offering an alternative to class components.
