Question

What is slice pipe in Angular Js?

Answer 1

The slice pipe is used to create a new Array or String containing a subset (slice) of the elements. The syntax looks like as below,

{{ value_expression | slice : start [ : end ] }}

For example, you can provide 'hello' list based on a greeting array,

@Component({
  selector: 'list-pipe',
  template: `<ul>
    <li *ngFor="let i of greeting | slice:0:5">{{i}}</li>
  </ul>`
})
export class PipeListComponent {
  greeting: string[] = ['h', 'e', 'l', 'l', 'o', 'm','o', 'r', 'n', 'i', 'n', 'g'];
}
