 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/).
 For those who prefer writing code by typescript, now React Social Network support both javascript and typescript language.
