ReactJS - Tutorial Comment System > Threaded commenting

Question

Im coming from this https://facebook.github.io/react/docs/tutorial.html

I like my users to reply to any comment, How can I use the same to add a reply to a comment

I like my children to be added when a reply button below the Comment is clicked, [ Exact functionality like Facebook :) ] Lets say I have the following JSON

    {  
  "comments":[
