With all due respect, the majority of large React projects I've encountered devolved into non-uniform big balls of mud that only the original authors can (sometimes) understand. React's "non-opinionated" stance constantly leads to a non-opinionated code base without a strong technical lead with a very firm hand.

When talking about other frameworks (sorry, "libraries"), React folks should really avoid throwing stones from their glass house.

I'm not fan of Angular by any means, but I totally respect how opinionated it is and how that translates out to development teams in the wild.
