How to use index in @for in html angular 18

How can I define the index variable in @for in Angular 17

const users = [
    { id: 1, name: 'Ali' },
    { id: 2, name: 'reza' },
    { id: 3, name: 'jack' },
  ];

<ul>
  @for (user of users; track user.id; let i = index) {
  <li>{{ user.name + i }}</li>
  } @empty {
  <span>Empty list of users</span>
  }
</ul>

index is not known as we had in *ngFor and got Unknown "let" parameter variable "index" in Angular17 @for

But the following is working:

<ul>
  <li *ngFor="let user of users; let i = index">{{ user.name + i }}</li>
</ul>
Solution

  • You can use $index everywhere in the scope of the @for block without having to alias it:

    <ul>
  @for (user of users; track user.id) {
     <li>{{ user.name + $index }}</li>
  } @empty {
     <span>Empty list of users</span>
  }
</ul>
