But the coding bootcamp's curriculum and sequencing isn't necessarily superior. It could be as arbitrary or suboptimal as any low-rated 1-star book on Amazon.

A curious programmer would actually be skeptical that the bootcamp has the proven syllabus for learning.

Therefore, find a 5-star book on Javascript/Ruby on Amazon, and start with Ch 1. What evidence (not marketing materials) would the novice programmer see that makes the coding bootcamp's sequencing superior to that?
