TanStack Query provides `injectQueries`, which you can use to dynamically execute as many queries in parallel as you'd like.

```ts
export class AppComponent {
users = signal<Array<User>>([])
// Please note injectQueries is under development and this code does not work yet
userQueries = injectQueries(() => ({
queries: users().map((user) => {
return {
queryKey: ['user', user.id],
queryFn: () => fetchUserById(user.id),
}
}),
}))
}
