1 - Explain the Angular component lifecycle hooks.
Answer: Angular provides lifecycle hooks that allow developers to perform specific actions at different stages of a component's lifespan, such as `ngOnInit`, `ngOnChanges`, and `ngOnDestroy`.
2) Describe the difference between a service and a directive in Angular.
Answer: Services are reusable, singleton classes that provide functionality across the application, while directives enhance the behavior or appearance of DOM elements within templates.
3) What is the purpose of dependency injection in Angular?
Answer: Dependency injection is a mechanism that allows Angular to automatically instantiate and provide dependencies to components and services, ensuring loosely coupled and maintainable code.
4) Explain the concept of data binding in Angular.
Answer: Data binding is a technique that automatically updates the DOM when the underlying data model changes, providing a seamless connection between the application state and the UI.
5) Describe the change detection algorithm in Angular.
Answer: Angular uses a change detection algorithm called “zone.js” to efficiently detect changes in the application state and update only the affected parts of the DOM.
6) What are the benefits of using TypeScript in Angular development?
Answer: TypeScript provides type safety, code navigation, and improved code quality by preventing errors and facilitating debugging.
7) Explain the concept of routing in Angular.
Answer: Routing allows for dynamic navigation between different views and components within an Angular app, ensuring a seamless user experience.
8) Describe how to handle HTTP requests in Angular.
Answer: Angular provides the `HttpClient` service to make HTTP requests, allowing for asynchronous data fetching, error handling, and response parsing.
9) What are the best practices for writing secure Angular applications?
Answer: Security best practices for Angular include using Angular security features, implementing cross site scripting (XSS) prevention, and following secure coding principles.
10) Explain how to test Angular components using unit testing.
Answer: Unit testing in Angular involves creating isolated tests for individual components, verifying their behavior and interactions using frameworks like Jasmine and Karma.
11 - Describe the role of observables in Angular.
Answer: Observables are a powerful mechanism in Angular for handling asynchronous data streams, providing a way to subscribe to events and receive updates in a reactive manner.
12) Explain the difference between AoT and JIT compilation in Angular.
Answer: AoT (Ahead of Time) compilation converts Angular templates into JavaScript during build time, improving application performance, while JIT (Just in Time) compilation happens at runtime, allowing for dynamic template generation.
13) Describe how to implement lazy loading in Angular.
Answer: Lazy loading allows for on demand loading of modules, reducing initial application size and improving performance by only loading necessary modules when needed.
14) Explain the concept of view encapsulation in Angular.
Answer: View encapsulation in Angular allows components to control how their styles are applied, preventing styles from bleeding into other components and ensuring encapsulated styling within components.
15) Describe the role of NgModules in Angular.
Answer: NgModules are modular containers that group related components, directives, pipes, and services, allowing for code organization, reusable code, and application level configuration.
