ANGULAR INTERVIEW QUESTION: Can you define what is a component in Angular?📦

A component is the most basic element🧬 of user interface in an Angular Application.

Furthermore, an Angular application can be viewed like a plain components tree.📦🌳

More precisely, a component is always composed of

―a TypeScript class for the business logic👨‍💼, with an @Component annotation, and of

―an HTML template🎨.

👇👇👇

Component snippet:

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

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
})

export class AppComponent {
    title = 'My App';
}

A component must always belong to a module to be used in your application or in another module.

Module snippet:

importˑˑ{ NgModule } from '@angular/core';
importˑˑ{ AppComponent } from './app.component';

@NgModule({
    declarations: [AppComponent],
    imports: [],
    bootsrap: [AppComponent]
})

export class AppModule {}
