1 - Explain the Angular lifecycle hooks.

• Answer: Initialization (ngOnInit), Change Detection (ngOnChanges), Control (ngDoCheck), View (ngAfterViewInit, ngAfterViewChecked), Destruction (ngOnDestroy)
• 2) Describe the difference between a service and a component in Angular.
•  Answer:* Services handle application wide functionality, while components represent UI elements. Services are reusable and can be injected into components.
• 3) What is the purpose of using Observables in Angular?
•  Answer:* To handle asynchronous data streams and manage data changes effectively. Observables emit values over time, allowing components to subscribe to and react to changes.
• 4) Explain the concept of dependency injection in Angular.
•  Answer:* Dependency injection is a mechanism that allows the automatic creation and injection of dependencies into a class or component. This helps maintain loose coupling and improves testability.
• 5) What are the advantages of using a routing module in Angular?
•  Answer:* Routing modules provide URL based navigation, define routes, and enable features like lazy loading. They help organize and manage application navigation, making it easier to maintain complex applications.
• 6) Describe the difference between template driven and reactive forms in Angular.
•  Answer:* Template driven forms use HTML templates to define the form and validation logic, while reactive forms use reactive programming techniques to create and manage forms programmatically. Reactive forms provide more flexibility and control over form validation and state management.
• 7) What is the purpose of the Angular CLI (Command Line Interface)?
•  Answer:* The Angular CLI is a command line tool that simplifies Angular development. It provides commands for creating, building, testing, and deploying Angular applications, making the development process more efficient.
• 8) Explain the concept of change detection in Angular.
•  Answer:* Change detection is a mechanism that detects changes in the application state and updates the DOM accordingly. It uses a zone based system to track changes and selectively update parts of the view that have been affected.
• 9) What are the best practices for optimizing Angular performance?
•  Answer:* Using Change Detection OnPush, lazy loading, optimizing data handling, and structuring applications effectively can improve performance.
• 10) Describe the process of creating and publishing an Angular library.
•  Answer:* Creating an Angular library involves defining the library's functionality, building it into a reusable package, and publishing it to a repository like npm.
• 11 - Explain how to handle HTTP requests in Angular.
•  Answer:* Angular provides the HttpClient service for handling HTTP requests. It offers methods for making GET, POST, PUT, and DELETE requests, and it supports advanced features like interceptors and error handling.
• 12) Describe the role of the Typescript interface in Angular development.
•  Answer:* Typescript interfaces define the structure and shape of data objects. They help ensure data consistency, improve code readability, and facilitate type checking during development.
• 13) Explain the concept of pure pipes in Angular.
•  Answer:* Pure pipes are functions that transform input data without modifying the original value. They are faster and more efficient than impure pipes because they avoid unnecessary change detection cycles.
• 14) Describe how Angular handles errors and exceptions.
•  Answer:* Angular provides error handling mechanisms through the try catch block, the ErrorHandler class, and the Angular ErrorHandler service. It allows developers to capture errors, log them, and provide user friendly error messages.
• 15) Explain the use of decorators in Angular.
•  Answer:* Decorators are metadata that modifies the behavior of a class or method. They are used in Angular to define components, directives, services, pipes, and other application related entities, allowing developers to extend the functionality of Angular itself.
