输入for循环反应+打字稿？

Question

我有 Todo 的这个界面：

export interface InitialTodoLoadingState {
  toggleComplete: boolean;
  updateText: boolean;
  deleteTodo: boolean;
}
export interface Todo {
  complete: boolean;
  _id: string;
  text: string;
  loading: InitialTodoLoadingState;
}

我正在尝试像这样循环一个 todos 对象数组：

const processing = todos // check if processing operations e.g.: toggle complete
      .map((todo: TodoInterface) => {
        for (let loadProp in todo.loading) {
          if (todo.loading[loadProp]) return true; // ERROR HERE
          return false;
        }
      })
      .some(process => !!process);

我收到一条错误消息：

Element implicitly has an 'any' type because type 'InitialTodoLoadingState' has no index signature.

我如何在这里实现打字稿？我不想使用任何

要删除错误，请添加索引签名（参见）：

export interface InitialTodoLoadingState {
  toggleComplete: boolean;
  updateText: boolean;
  deleteTodo: boolean;
  [key: string]: boolean;
}
