Question 4. What are the different perks of React Native mobile app development?

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

Question 5. How to Get React Native Map Feature?

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

import React, {Component} from ‘react’;

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

export default class Home extends Component {

  constructor(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 => {

      return (

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







  render() {

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



Question 6. What is hot reloading?

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

Hot ReloadingLive Reloading
Real-time upgradation while managing the code source without disturbing the real state.Live reloading refers to the spot reloading after changes occur in the codebase.
It also shows the code changes in response to new code modifications without having to restart the app from the beginning.It restarts the app in case of any modification in the code.

Question 8. 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 9. Can we use the same codebase for both iOS and Android Development?

Yes, developers use the same code base 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 10. Define props and how it works in React Native?

Props stand for property in React as it helps to transfer data from one component to another. The data can not modify as it is on the read-only option. They’re handy when you want your app’s data flow to be dynamic.

Question 11. 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 12. Which industry uses React Native?

The top-most companies are listed below:

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

Question 13. Is It Possible To React Natively 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 14. Can 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 to separate Android and iOS logic, allowing you to make them appear and behave differently while still sharing the majority of the functionality.

Question 15. What are the main benefits of leveraging 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 easiness, 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.
