import { computed, ComputedRef } from 'vue';

export function followDescendantsByName<
  ReactiveParent,
  ChildKeys extends ReadonlyArray<keyof ReactiveParent>,

    childKeys.map((childKey) => {
      return [childKey, computed(() => parentSelector()[childKey])];
    }),
  ) as {
    [childKey in ChildKeys[number]]: ComputedRef<ReactiveParent[childKey]>;
