Angular Interview Questions For Fresher

Angular interview questions for freshers are essential for employers to assess a candidate's foundational knowledge and practical skills in this popular front-end web framework. By probing into topics such as component architecture, data binding, routing, and change detection, interviewers can gauge the candidate's understanding of core Angular concepts and their ability to apply them in real-world scenarios. These questions not only serve as a screening tool but also provide valuable insights into the candidate's problem-solving abilities and overall approach to web development.

1 - Explain Angular's component lifecycle methods: ngOnInit, ngOnChanges, ngAfterViewInit, ngOnDestroy.

2) What is dependency injection in Angular? It allows components to request other services or objects they need.

3) Describe Angular's routing mechanism: Routing allows navigation between different views in an Angular application.

4) How does Angular handle data binding? Angular uses data binding to synchronize data between the model and the view.

5) Explain the difference between ngFor and ngIf directives: ngFor iterates over a collection and creates a template for each item, while ngIf conditionally displays or hides an element.

6) What is the purpose of the Angular CLI? It provides a command line interface for scaffolding and maintaining Angular applications.

7) Describe the concept of observables in Angular: Observables represent streams of data that can be subscribed to for updates.

8) Explain the difference between synchronous and asynchronous operations in Angular: Synchronous operations execute immediaile asynchronous operations occur after a delay.

9) What is the importance of encapsulationr components? Encapsulation helps prevent unwanted side effects and promotes code organization.

10) Describe Angular's change detection strategy: Angular uses a zone based change detection strategy to detect and respond to changes in the application state.

11 - Explain the role of services in Angular: Services provide shared functionality and data across components.

12) What are the best practices for testing Angular applications? Use unit testing and end to end testing to ensure code quality and robustness.

13) Describe the concept of modules in Angular: Modules group related components, directives, and services together.

14) Explain the difference between class components and template based components in Angular: Class components use the TypeScript class syntax, while template based components use HTML templates.

15) What is the purpose of the Angular expression language? It allows developers to bind data and create dynamic templates.
