That doesn't say much about React, though. Indeed, you can open the network panel and watch requests go by over the seconds that it takes to open, suggesting that the issue likely resides on the backend.
Or are you implying that React does not fit FB use case?
Are you just going to defend React to the bitter end? Or do you just enjoy imaginary binary choices?
I don't defend React. My question was almost the opposite and I was trying to ask:
So if even Facebook has a problem with using React then who has a better examplea about why and how to use it?
