Question 5. What are the different perks of React Native app development?

• Exceptional animated UI components.
• Highly cost-effective and time-saving.
• Fastest development and quick market launch.
• Simple to integrate APIs and on other platforms. 
• Easy code readability because of JSX use.
• Reusable codebase and utilization.

Question 6. How to Get the React Native Map Feature?

The use of the Map feature is to screen the list of elements in an array. See the example below:

import React, {Component} from ‘react’;

import {Text, View} from ‘react-native’;

export default class Home extends Component {

  constructor(props) {

    super(props);

    this.state = {

      array: [

        {

          key: ‘1’,

          title: ‘example title 1’,

          subtitle: ‘example subtitle 1’,

        },

        {

          key: ‘2’,

          title: ‘example title 2’,

          subtitle: ‘example subtitle 2’,

        },

        {

          key: ‘3’,

          title: ‘example title 3’,

          subtitle: ‘example subtitle 3’,

        },

      ],

    };

  }

  list = () => {

    return this.state.array.map((element) => {

      return (

        <View key={element.key} style={{margin: 10}}>

          <Text>{element.title}</Text>

          <Text>{element.subtitle}</Text>

        </View>

      );

    });

  };

  render() {

    return <View>{this.list()}</View>;

  }

}

Question 7. What is hot reloading in React Native app development? 

React Native hot reloading is a plugin that manages the code of apps while the app is running. Moreover, it doesn’t affect the performance and state of the app, and also no need to reload the app after adding any feature.

Question 8. What’s the difference between hot reloading and live reloading?

Question 9. What does fabric mean in React Native?

Fabric seeks to reconstruct the React rendering native layer. All UI activities are handled by a series of cross-bridge phases in the present interoperability.

Question 10. Can we use the same codebase for both iOS and Android Development? 

Yes, developers use the same code for both platforms. That’s what React Native is known for. It helps build apps faster and saves the cost of reusable code instead of writing code separately for each platform. 

Question 11. Define props and how they work in React Native?

Props stand for properties in React, as they help to transfer data from one component to another. The data can not be modified as it is in the read-only mode. They’re handy when you want your app’s data flow to be dynamic.

Question 12. What is Redux?

The Redux pattern is a state management pattern. It enables us to keep your JavaScript apps in a predictable state container. In fact, any frontend framework, such as React, can utilize the Redux library. Install the react-redux dependency to add Redux to your React application.

Question 13. Which industry uses React Native?

The top-most companies are listed below:

• Facebook
• Pinterest
• UberEats
• Airbnb
• Instagram
• Skype
• Walmart
• Wix
• Tesla

Question 14. Is It Possible To React Native With Existing Apps?

Yes, as long as your app does not rely on the smartphone doing significant processing activities. React Native’s capabilities are highly unpredictable, allowing it to be used to create increasingly sophisticated apps. Furthermore, transitioning to React Native reduces the cost of maintaining your project because there is only one codebase for both Android and iOS. 

Question 15. Can the Android and iOS apps have a distinct look and appearance?

Yes! However, this comes at a cost because it must create the code for each device separately. Even still, it’s far less expensive than creating two native apps. React Native was designed in a way that separates Android and iOS logic, allowing you to make them appear and behave differently while still sharing the majority of the functionality.

React Native Versus a Native Solution

Cross-platform development has emerged as a viable option for developing only native mobile apps. The main advantage of this method is that it reduces development time and expenses. Because of reusable code and pre-built components, this is possible.

With React Native’s ease, developers don’t have to create a separate mobile app for each platform because 80-90 percent of a codebase may be shared across platforms, depending on the application’s complexity. Furthermore, the JavaScript development team may use this framework to create efficient software for iOS and Android without learning the intricacies of each OS’s environment.
