Angular 8 面接の質問と回答

Question: What are Angular services and why are they used?

Answer: Services in Angular are singleton objects that provide functionality across the application. They are used to encapsulate and share logic, data, or functionality between components. Services promote modularity and reusability in Angular applications.

Example:

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root',
})
export class DataService { }
