This article purposefully misrepresents React in favor of the author's own framework Binding.scala, all the criticism are either superficial like class being className (which is a good thing because JSX is not HTML) or has nothing to do with React like JavaScript's dynamic typing system and handling of asynchronous updates.

He also seems to believe that React is framework when it's a library, if his knowledge of React is so shallow that he didn't even read the first sentence on the React website I can't take his opinions on it seriously.

I don't like these kinds of articles which are only thinly veiled advertisements that do not offer any thoughtful criticisms, what I would really like is to hear from someone who has actually worked on a huge project which includes React and what troubles if any they ran into.
