How to get the reactive length of a reactive list?

[sarat1669]

  const items = reactive([]);
  const length = derive(() => Object.keys(items).length);

  return div(
      list(div, items, ({ val: v }, deleter) =>
        div(() => v, div({ onclick: deleter }, "❌"))
      ),
      div(() => `You have ${length.val} item(s)`),
      span(() => Object.keys(stateFields(items)).length),
      button({ onclick: () => items.push(items.length + 1) }, "Add Item")
  )

Both of these values are always 0

[Tao-VanJS]

van.derive(() => Object.keys(items).length)

should work. This example illustrates that.
