I was reading about React-Redux provider in the library docs and i faced 'context instance' prop as one prop for the provider, i couldn't really understand what it means:我正在图书馆文档中阅读有关React-Redux 提供者的信息，我遇到了“上下文实例”道具作为提供者的一个道具，我无法真正理解它的含义：

context You may provide a context instance. If you do so, you will need to provide the same context instance to all of your connected components as well. Failure to provide the correct context results in runtime error:

Is it the whole store data??是全店数据吗？？ the destination component of data??数据的目标组件？？

No, the context props is a react context instance, which allow you using store directly in its consumer instead of through connect , useSelector or useStore .不， context道具是一个反应上下文实例，它允许您直接在其消费者中使用store ，而不是通过connect 、 useSelector或useStore 。 As its doc, you can either create your custom context or using redux's ReactReduxContext作为其文档，您可以创建自定义上下文或使用 redux 的ReactReduxContext
