如何让*ngFor随机显示？

import { Component } from '@angular/core';

@Component({
  selector: 'app-random-ngfor',
  template: `
    <div *ngFor="let item of randomItems">{{ item }}</div>
  `,
})
export class RandomNgForComponent {
  items: string[] = ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5'];

  get randomItems(): string[] {
    return this.shuffleArray(this.items);
  }

  shuffleArray(array: any[]): any[] {
    let currentIndex = array.length;
    let temporaryValue;
    let randomIndex;

    while (currentIndex !== 0) {
      randomIndex = Math.floor(Math.random() * currentIndex);
      currentIndex -= 1;

      temporaryValue = array[currentIndex];
      array[currentIndex] = array[randomIndex];
      array[randomIndex] = temporaryValue;
    }

    return array;
  }
}
