Updated Syntax

The instructor in this's course used an old way to add (input) syntax, this's way not working in the new version of angular. it's updated

 @Component({
  selector: 'app-artist-details',
  templateUrl: './artist-details.component.html',
  inputs: ['artist']
}) 

• We should add the input like this

export class ArtistDetailsComponent {
  @Input('artist') artist: any;
}

you can learn more about input and component in angular docs
