如何在Angular中对json数组进行切片

ng generate pipe slice

transform(value: any[], start: number, end: number): any[] {
  return value.slice(start, end);
}

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

@Component({
  selector: 'app-example',
  template: `
    <div *ngFor="let item of slicedArray | slice:0:3">{{ item }}</div>
  `,
  providers: [SlicePipe]
})
export class ExampleComponent {
  array: any[] = [
    { name: 'Item 1' },
    { name: 'Item 2' },
    { name: 'Item 3' },
    { name: 'Item 4' },
    { name: 'Item 5' }
  ];
  slicedArray: any[];

  constructor(private slicePipe: SlicePipe) {
    this.slicedArray = this.slicePipe.transform(this.array, 0, 3);
  }
}
