Angular-da siklni juft iteratsiyasi

*ngFor va @for orqali aylantirishda even o‘zgaruvchisi yordamida siklni juft iteratsiyasini aniqlash mumkin.

*ngFor direktivasi uchun misol:

app/app.component.html<ul>
  <li *ngFor="let el of arr; let even = even">
    {{ even ? 'juft' : 'yo‘q' }}
    {{ el }}
  </li>
</ul>

@for konstruksiyasi uchun misol:

app/app.component.html<ul>
  @for (el of arr; track $index) {
    <li>
      {{ $even ? 'juft' : 'yo‘q' }}
      {{ el }}
    </li>
  }
</ul>

app/app.component.tsexport class AppComponent {
  public arr: string[] = ['a', 'b', 'c', 'd'];
}
