1 - What is Angular?   Angular is an open source web application framework maintained by Google that uses TypeScript.

2) What are the key features of Angular?   Features include: component based architecture, dependency injection, change detection, and routing.

3) What is the purpose of a component in Angular?   Components are reusable building blocks that encapsulate both the view (UI) and the logic (behavior) of a web application.

4) What is dependency injection in Angular?   Dependency injection is a pattern that allows you to provide dependencies to components at runtime, ensuring loose coupling and testability.

5) What is the role of change detection in Angular?   Change detection is a mechanism that automatically detects changes in the application state and updates the UI accordingly, enhancing performance and responsiveness.

6) Explain the concept of routing in Angular.   Routing allows you to navigate between different views in your application, enabling users to interact with various parts of the application.

7) What are the different routing strategies in Angular?   Routing strategies include hash based routing, path based routing, and redirect based routing.

8) What is the purpose of a service in Angular?   Services are reusable, singleton objects that provide functionality to components, promoting code reusability and modularity.

9) Describe the difference between a template and a component.   Templates contain the UI logic and are normally associated with a single component, while components combine templates and logic to create reusable and maintainable code.

10) What are the best practices for writing modular and maintainable Angular code?   Best practices include: using services to provide functionality, separating concerns into different modules, and employing lazy loading to improve performance.

11 - Explain the purpose of Observables in Angular.   Observables are a reactive programming pern that allows you to handle asynchronous events and data streams, enhancing code clarity and responsiveness.

12) What are the testing strategies for Angular applications?   Testing strategies include: unit testing, integration testing, and end to end testing.

13) How do you handle security concerns in Angular applications?   Security measures include: implementing authentication and authorization, preventing cross site scripting attacks, and avoiding SQL injections.

14) What are the recent trends and advancements in Angular?   Recent advancements include: the introduction of Angular Material, the Ivy rendering engine, and the Angular Elements library.

15) How do you keep up with the latest updates and best practices in Angular development?   Stay informed by following official Angular documentation, blogs, and community forums.
