type State = {
  Domains: Domain list
  Counter: int
}

// Imagine having a function somewhere dat increments our counter automatically (or manual whatever floats your boat)

let view .... =
  div [] [
    counter state.Counter
    SomeComponent.render {| Domains = state.Domains |> List.filter (fun d -> d.Selected } |}
  
  ]
  
  
// Every time the counter gets incremented the state changes. 
// View fn picks up that state change and filters the domains again (which havent been changed)
// That results in a new list and our function component gets rerendered.
