Welcome to our web story on mastering Angular interviews. Are you ready to ace your next Angular interview? Let's dive into the top interview questions and expert explanations to help you prepare effectively.
What are Angular Components?
Angular components are the building blocks of an Angular application. They encapsulate the behavior and presentation of a UI element. A component consists of a template, class, and metadata
Explain Angular Services.
Angular services are singletons that provide shared functionality across components. They are used to manage data, handle business logic, and perform operations like HTTP requests.
What are Angular Directives?
Angular directives are instructions in the DOM that Angular interprets. They add behavior to elements or transform the DOM. Examples include ngFor, ngIf, and ngStyle.
How does Angular Routing work?
Angular routing allows navigation between different components without a full-page reload. It's achieved through the RouterModule, which provides configuration for routes and navigation paths.
Define Dependency Injection
Dependency Injection (DI) is a design pattern used in Angular to manage object creation and relationships. It enables components to request dependencies from the injector, making code modular, testable, and easier to maintain.
Explain Angular Lifecycle Hooks.
Angular Lifecycle Hooks are methods that allow you to tap into specific moments of a component's lifecycle. Examples include ngOnInit, ngOnDestroy, and ngOnChanges. Understanding these hooks helps manage component initialization and clean-up.
How are Angular Pipes used?
Angular Pipes are built-in tools that transform data in templates. They format data for display, filter lists, and perform other operations. Pipes provide a convenient way to modify data without altering the underlying source.
What are Angular Modules?
Angular Modules organize an application into cohesive blocks of functionality. They help manage the application's complexity by providing a way to encapsulate components, services, and directives. Modules enhance modularity and maintainability.
Explain Angular Change Detection?
Angular Change Detection is a mechanism that updates the view based on changes in the application's state. Angular uses a tree of components and a change detection strategy to efficiently update the DOM when data changes.
