**Q1. What is Ionic Framework?**
Ans: Ionic Framework is an open-source UI toolkit for building cross-platform mobile applications using web technologies like HTML, CSS, and JavaScript. It allows developers to create native-like experiences across multiple platforms with a single codebase.

**Q2. What are the key features of Ionic Framework?**
Ans: There are following key features of Ionic Framework include:

Cross-platform compatibility
Built-in UI components
Theming and customization
Native device features integration
Performance optimization
Community support and plugins
**Q3. Explain the difference between Ionic and Cordova.**
Ans: Ionic is a UI toolkit that provides a set of pre-designed UI components and tools for building mobile applications, while Cordova is a platform for building mobile applications using web technologies by wrapping them in a native container.

**Q4. What is Angular in the context of Ionic Framework?**
Ans: Angular is a popular JavaScript framework for building web applications, and Ionic Framework is built on top of Angular. Angular provides features like data binding, dependency injection, and routing, which are leveraged by Ionic for building robust mobile applications.

**Q5. What is Capacitor, and how does it relate to Ionic Framework?**
Ans: Capacitor is a cross-platform runtime and native API layer for web applications. It enables web developers to build native mobile applications using web technologies and deploy them to multiple platforms. Capacitor is commonly used in conjunction with Ionic Framework for building cross-platform mobile apps.

**Q6. What is the role of CLI in Ionic Framework development?**
Ans: CLI (Command Line Interface) in Ionic Framework is a powerful tool that streamlines development tasks such as project setup, code scaffolding, building, testing, and deployment. It provides commands for creating, serving, and building Ionic applications, making development faster and more efficient.

**Q7. Explain the concept of lazy loading in Ionic Framework.**
Ans: Lazy loading is a technique used to improve the performance of Ionic applications by loading modules, components, or resources only when they are needed. In Ionic Framework, lazy loading is achieved by dynamically loading modules and components when the user navigates to a specific route, reducing initial load times.

**Q8. How can you handle device-specific features in Ionic applications?**
Ans: Ionic provides plugins and APIs for integrating device-specific features such as camera, geolocation, accelerometer, and push notifications into your applications. These plugins allow developers to access native device capabilities using JavaScript code and provide a consistent user experience across different platforms.

**Q9. What is the significance of Ionic Native in Ionic Framework development?**
Ans: Ionic Native is a library of TypeScript wrappers for Cordova/PhoneGap plugins and other native device APIs. It simplifies the process of integrating native device features into Ionic applications by providing a consistent and easy-to-use API layer that abstracts away platform differences.

**Q10. How do you debug Ionic applications?**
Ans: Ionic applications can be debugged using browser developer tools like Chrome DevTools or Firefox Developer Tools. By running your Ionic app in a browser, you can inspect and debug HTML, CSS, and JavaScript code, set breakpoints, and analyze network requests for troubleshooting and optimization.
