 如果不想使用 store 的 data 体系，也可以使用发布订阅模式。比如在 Omi 中使用 [mitt](https://github.com/developit/mitt) 跨组件通讯:

 ## Mitt
 
 If you don't want to use store's data system, you can also use publish subscribe mode. For example, using [mitt](https://github.com/developit/mitt) across component communication in Omi:

 If you want to be compatible with IE11, please use the `omi-mobx` instead of omi's own observe.
