Hi.
I did this lesson - https://youtu.be/IvoeACm8hI4.
There is my code - http://codepen.io/SerafimPoch/pen/VPgNrN?editors=0010
But it dosen’t works 
. I guess I need to create another component which will call - Comment. Please, chek my code, maybe I have mistakes.
And write what I should do to pass this lesson. Thank you.
Check what component you render into the DOM.
