 The React Social Network is an open source project relying on [React](https://facebook.github.io/react/docs/hello-world.html) a powerful javascript library for building the user interface. In this project, I tried to show some features of react/react components as a social network.

 Since I started building this project I've planned to have a back end for this project so I haven't focused on performance until I build the back end and move some data procedure from end to back end. Therefore I need to change data structure and actions for [Redux](http://redux.js.org/).
