@Component({
  selector: 'app-filter-display',
  imports: [OperatorPipe],
  template: `
    <span [innerHTML]="filter | operator"></span>
  `
})
export class FilterDisplayComponent {
  filter = { 
    operator: 'gte', 
    value: '100' 
  };
  
  // Will display as "≥ 100"
  
  betweenFilter = { 
    operator: 'between', 
    start: '10', 
    end: '20' 
  };
  
  // Will display as "> 10 ≤ 20"
}

Notes

The output of this pipe contains HTML entities, so it should be used with the [innerHTML] binding in Angular templates to render properly.
