What is the purpose of the ViewChild decorator in this component class?

    . . .
    template: '<p #bio></p>'
    export class UserDetailsComponent {
    @ViewChild('bio') bio;
  •  It provides access from within the component class to the ElementRef object for the <p> tag that has the bio template reference variable in the component’s template view.
  •  It indicates that the <p> tag be rendered as a child of the parent view that uses this component.
  •  It makes the <p> tag in the template support content projection.
  •  It makes the <p> tag visible in the final render. If the #bio was used in the template and the @ViewChild was not used in the class, then Angular would automatically hide the <p> tag that has #bio on it.
