SlicePipe

pipe

Creates a new Array or String containing a subset (slice) of the elements.

  
    class SlicePipe implements PipeTransform {
}

All behavior is based on the expected behavior of the JavaScript API Array.prototype.slice() and String.prototype.slice().

When operating on an Array, the returned Array is always a copy even when all the elements are being returned.

When operating on a blank value, the pipe returns the blank value.

This ngFor example:

produces the following:

          <li>b</li><li>c</li>
