@angular/core

As explained in Pro Angular 16

@angular/core is the Angular package that provides foundational framework functionality, including component support.

@angular/core supplies foundational Angular functionality, including the Component type used to define application components. section 2.3.3

Import Component from @angular/core, then configure a class with @Component metadata such as selector, templateUrl, and styleUrls. section 2.3.3

Todo application root component

AppComponent imports Component, declares the app-root selector, connects external template and stylesheet files, and exposes TodoList data through username and itemCount getters. section 2.3.3
