This pisses me off so much! The guy doesn't understand why he might need redux and does not understand what problems it is trying to solve (or he hasn't encountered these problems yet), and also doesn't quite understand how React works (because then it would be really obvious why a plain object is not enough). Which is totally fine. What is not fine is that he then goes to an interview and talks about redux. Also, this "how was I supposed to answer this"? Ugh!
And then we have all these reddit/hacker news threads about how redux is horrible and why doesn't it just die.
