I guess it depends what one thinks is representative of a hello world. His first print out of the literal "hello world" may be down that far, but in terms of "classical" hello world "standards" (just based off what hello world apps have traditionally looked like), the section I linked is more analogous in my opinion. It shows react operational and rendering. If the bar is a yelp clone (which is already contrary to what a hello world is), then sure, maybe page 93 is more apt. But...you're building a yelp clone.
