@paramopts{ debugName?: string | undefined; } | undefined

@returnsSignal<readonly LocatorT[]>

function viewChildren<LocatorT, ReadT>(locator: string | ProviderToken<LocatorT>, opts: { read: ProviderToken<ReadT>; debugName?: string | undefined; }): Signal<readonly ReadT[]>;

Usage Notes

Create a children query in your component by declaring a class field and initializing it with the viewChildren() function.

          @Component({...})export class TestComponent {  divEls = viewChildren<ElementRef>('el');   // Signal<ReadonlyArray<ElementRef>>}
