我在我的网站控制台中遇到了这个错误，然而，我不知道错误是从哪里来的，有没有什么可以追查的错误代码在哪里？
这很可能是因为我在Reaction组件中使用了一些嵌套对象，而实际上它可能包含相同子键，如:x["cat"][1],x["dog"][1]，这样定义对象有什么不对吗？或者这不是问题所在？
app-index.js:31 Warning: Encountered two children with the same key, `0`. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.
