1 - What are the main advantages of using React Native?
Cross platform development
Reusable codebase
Fast development time
Native like performance
2) Explain the concept of state in React Native.
State is a mutable object that holds data relevant to the component's rendering.
Changes to the state trigger re rendering of the component and its children.
3) What is the difference between props and state?
Props are immutable objects that are passed down from parent components.
State is mutable and is managed by the component itself.
4) How do you handle navigation in React Native?
Use the React Navigation library to create a stack or tab based navigation system.
5) Explain the concept of lifecycle methods in React Native.
Lifecycle methods are invoked at different stages of a component's lifecycle, such as `componentDidMount`, `componentDidUpdate`, and `componentWillUnmount`.
6) What are the different types of animations in React Native?
Layout animations: animate changes to the layout of components.
Animated API: allows for custom animations and interpolation of values.
7) How do you handle asynchronous operations in React Native?
Use `async/await` syntax or Promise based APIs.
8) What are the best practices for performance optimization in React Native?
Use `shouldComponentUpdate` to prevent unnecessary re renders.
Avoid using inline styles and use StyleSheet instead.
Optimize images and other assets.
9) How do you integrate native modules into React Native?
Use the `NativeModules` module to access native code from JavaScript.
10) What are some of the popular React Native libraries?
React Navigation, Redux, Expo, Axios, Moment.js
- Increase your activity level. The more active you are, the more points you'll earn. Aim to get at least 30 minutes of moderate intensity activity or 15 minutes of vigorous intensity activity each day.
- Log your food.* Keeping track of your food intake can help you make healthier choices and earn more points. Be sure to log everything you eat and drink, even small snacks.
- Join a support group.* Joining a support group can provide you with motivation and encouragement from others who are also trying to lose weight.
- Set realistic goals.* Don't try to lose too much weight too quickly. Aim to lose 1 2 pounds per week.
