dictify(array, opts)

Make array into dict

  include: {
    lists: "id",
    "namespace.inners": "id"
  }
};

const array = [
  { id: 1, lists: [{ id: 1 }] },
  { id: 2, lists: [{ id: 1 }] },
  {
    id: 3,
    lists: [{ id: 1 }],
    namespace: {
      inners: [{ id: 1 }, { id: 2 }, { id: 3 }]
    }
  }
