1 - Difference between Angular 1 and Angular 2:
Angular 2 is a complete rewrite of Angular 1, with a focus on modularity, performance, and developer experience.
2) Explain the concept of modules in Angular 2:
Modules are containers for related code, such as components, directives, and services. They provide a way to organize and encapsulate functionality.
3) What are the key features of Angular 2's dependency injection system?
Singletons: Dependency injection provides a way to create and manage dependencies between components and services.
Lifetime management: It allows you to control the lifetime of dependencies, ensuring they are available when needed and destroyed when no longer required.
4) Describe the role of RxJS in Angular 2:
RxJS is a library for reactive programming, which allows you to deal with asynchronous events in a declarative and composable way.
5) What are the advantages of using TypeScript in Angular 2?
TypeScript provides static typing, which helps catch errors at compile time and improves code maintainability.
6) Explain the lifecycle of an Angular 2 component:
The lifecycle of a component consists of several phases, including initialization, change detection, and destruction.
Understanding the lifecycle is crucial for managing component state and optimizing performance.
7) What are the recommended best practices for designing and building Angular 2 applications?
Follow a modular approach, use dependency injection, embrace reactive programming, and implement proper testing strategies.
8) Experience with Angular Material:
Have you worked with Angular Material, a library for building responsive, cross platform UI components?
Can you discuss your experience with using and customizing its features?
9) Experience with Angular Routing:
Have you implemented routing in Angular 2 applications?
Can you explain how you handled URL navigation, lazy loading, and route parameters?
10) Testing in Angular 2:
Have you used unit testing frameworks like Jasmine or Karma to test Angular 2 components and services?
Can you discuss your approach to testing and the techniques you have employed?
11 - Performance optimization in Angular 2:
Have you encountered performance issues in your Angular 2 applications?
Can you describe the techniques you have used to identify and resolve performance bottlenecks?
12) Experience with third party libraries in Angular 2:
Have you integrated third party libraries into Angular 2 applications?
Can you provide examples of libraries you have used and how you have utilized them?
13) Cross platform development with Angular 2:
Have you developed Angular 2 applications that target multiple platforms, such as web, mobile, or desktop?
Can you discuss the challenges and solutions you have encountered in cross platform development?
14) Experience with Angular CLI:
Have you used the Angular CLI to create and manage Angular 2 projects?
Can you explain how the CLI has streamlined your development workflow?
15) Stay up to date with Angular 2:
How do you stay up to date with the latest developments in Angular 2?
Have you attended conferences or read technical articles to expand your knowledge?
