Misleading title. Does not show how "principled" coders outperform. Doesn't even define what "outperform" might mean in context, or who coders compete with and when that might happen. Offers a very high-level overview of Bob Martin's SOLID principles with no attribution, and a quick run-through of design patterns, again with no attribution. Does not show how adopting those ideas improves code or leads to outperforming the imagined competition.
