In Angular, a component is a building block of the application that encapsulates the view, data, and behavior. It is defined using the @Component decorator and can have its own template and styles. A directive, on the other hand, is a class that can modify the behavior or appearance of an existing DOM element. Directives are defined using the @Directive decorator and do not have their own view. Components can be seen as a specialized type of directive that has a view.
How to Answer ItWhen answering this question, clearly define both terms and highlight their differences. Use examples to illustrate your points, such as mentioning how components are used to create reusable UI elements, while directives are used to enhance existing elements.
State management in Angular can be achieved using services, RxJS, and state management libraries like NgRx or Akita. Services can hold the application state and provide methods to update it. RxJS observables can be used to reactively manage state changes and communicate between components. NgRx provides a more structured approach with actions, reducers, and a store to manage state in a predictable manner.
How to Answer ItDiscuss the various methods of state management, emphasizing the use of services and observables. If applicable, mention any libraries you have used and how they improved your application's state management.
Observables are a core part of RxJS and provide a way to handle asynchronous data streams. Unlike promises, which handle a single value, observables can emit multiple values over time and can be canceled. Observables are lazy, meaning they only execute when subscribed to, while promises are eager and execute immediately. This makes observables more powerful for handling events and data streams in Angular applications.
How to Answer ItExplain the concept of observables and their advantages over promises. Use examples to illustrate scenarios where observables are more beneficial, such as handling user input or API responses.
Dependency injection (DI) is a design pattern used in Angular to manage the dependencies of components and services. It allows a class to receive its dependencies from an external source rather than creating them internally. This promotes modularity and testability, as dependencies can be easily swapped or mocked. Angular's injector is responsible for creating and providing instances of services to components that require them.
How to Answer ItDefine dependency injection and its benefits, such as improved testability and modularity. Provide examples of how DI is implemented in Angular, including the use of the @Injectable decorator.
Lazy loading is a technique in Angular that allows modules to be loaded on demand rather than at the initial application load. This improves performance by reducing the initial bundle size and loading only the necessary code when a user navigates to a specific route. Lazy loading is implemented using the Angular Router, which can be configured to load modules asynchronously.
How to Answer ItExplain the concept of lazy loading and its benefits for application performance. Discuss how to implement lazy loading in Angular using the Router and provide examples of scenarios where it is particularly useful.
