Lets say I have the following getter/setter methods

get next() {
  console.log(this.people[this._index], this._index);
  return this.people[this._index];
}

set next(i: any) {
  this._index = (+i) + 1;
  this._index = (+i) % this.people.length;
}

and I want to call this in the following way:

<ng-template ngFor let-person="$implicit" [ngForOf]="people" let-i=index let-last=last>
  <app-card [cardItem]="people[i]" [nextCard]="next(i)"></app-card>
</ng-template>

PS: Think of this as circular array. Where by I need prev, current, and next items.

However I get the following Error

Angular: Member 'next' in not callable

Why is that? And whats the solution?

Thanks

Edit

Thank you guys for your help and explanation. With your help i managed to make it work:

<app-card [currentCard]="people[i]" [nextCard]="people[i === people.length - 1 ? 0: i + 1]" [prevCard]="i == 0 ? people[people.length - 1] : people[i - 1]"></app-card>

So its pretty much circular array. Lets assume we have the following:

people["James Dan", "Aluan Haddad", "Jota Toledo"]

So few conditions:

1. If I stand in the beginning of the array (i.e. index = 0) - then my prev will be people[people.length - 1] which is the last element in the array. And if my current is on index 1, then my prev will be index 0 and next will be index 2.
