> If you were trying to learn Rails (which this story ostensibly is doing with React) you wouldn't have Ruby installed Why? I went to Rails after I learnt Ruby. By that time, I already had rvm installed to manage Rubies. I can agree that a lot of users jump to Rails without learning Ruby first, in which case the setup will be 4 commands longer. But that is not the case with React as you can't jump over JavaScript to React directly.
