6. What is the difference between Ionic Framework and native mobile app development?
Ans: The main difference between Ionic Framework and native mobile app development is that Ionic Framework uses web technologies to build hybrid mobile applications, while native mobile app development uses platform-specific programming languages and tools to build native mobile applications.
7. What is the difference between “ionic build” and “ionic prepare”?
Ans:
| Ionic Prepare | Ionic Build |
|---|---|
| To prepare an Ionic project for a specific platform, developers can use the command “ionic prepare <platform>”. This command serves the purpose of copying all the relevant files from the project’s www folder into the www folder of the target platform. This ensures that the project is properly configured and ready to run on the desired platform. In other words, the “ionic prepare <platform>” command helps to streamline the process of preparing an Ionic project for deployment on a specific platform. | When developing an Ionic application, developers can use the “ionic build <platform>” command to prepare and build their code for deployment on a specific platform. This command not only performs the tasks of “ionic prepare”, but also builds the application’s source code. The end result is an executable version of the application that can be run on a simulator, emulator, or device. In summary, the “ionic build <platform>” command is a useful tool for simplifying the process of building and preparing an Ionic application for deployment on a specific platform. |
8. What is the role of Angular in Ionic Framework?
Ans: Angular is a popular JavaScript framework that is used to build web applications. Ionic Framework uses Angular to provide a robust and structured architecture for building hybrid mobile applications.
9. What is the difference between Ionic Framework and React Native?
Ans: The main difference between Ionic Framework and React Native is that Ionic Framework uses web technologies to build hybrid mobile applications, while React Native uses platform-specific programming languages and tools to build native mobile applications.
10. In Ionic, what are the various page life-cycle events?
Ans: Ionic leverages the Angular life-cycle events, which include:
- ngOnInit: A one-time event that occurs during component initialization. It can be utilized for setting up local members and making one-time calls to services.
- ngOnDestroy: An event triggered shortly before the view is destroyed by Angular. It’s helpful for tasks like unsubscribing from observables and cleaning up.
- ionViewWillEnter: Invoked when the component routing-to is going to animate into view.
- ionViewDidEnter: Fired when the component routing-to has finished animating.
- ionViewWillLeave: Triggered when the component routing-from is about to animate.
- ionViewDidLeave: Fired when the component routing-to has finished animating.
There are additional lifecycle events that can prevent users from gaining unwanted access:
- ionViewCanEnter: Called before entering a view, allowing you to control whether or not the view can be accessed by the user.
- ionViewCanLeave: Activated before the user can leave a view and allows you to control whether the view can be left or not.
In Ionic 4, these events can be replaced by using Routing Guards.
11. What are the page life-cycle hooks in Ionic 4?
Ans: Ionic hooks have three different life-cycle events.
- ionNavDidChange event is fired when the nav has changed components.
- ionNavWillChange event is fired when the nav will change components.
- ionNavWillLoad event is fired when nav will load a component.
12. What is the role of the Angular router in Ionic Framework?
Ans: The Angular router is used in Ionic Framework to provide navigation between pages and components in hybrid mobile applications.

Ans: The main difference between Ionic Framework and Flutter is that Ionic Framework uses web technologies to build hybrid mobile applications, while Flutter uses its own programming language and framework to build native mobile applications.
14. How do you explain events in Ionic?
Ans: Ionic Events is a powerful publish-subscribe system that enables messages to be sent and received across multiple components and pages within an app. Essentially, it serves as a framework for facilitating communication and response to app-level events throughout your entire application. By leveraging Ionic events, you can easily incorporate user interactivity into your app through a variety of available options. A comprehensive list of all Ionic events is provided in the table below for reference.
| Event Name | Event Detail |
|---|---|
| on-hold | Called when touch duration is greater than 500ms. |
