On: If not React, then what?

[gls2ro]

I think I was not clear in my question:

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?

Like I said, React has nothing to do with the slowness issues of messenger.com.
