Martin wrote it in a really approachable means, and what I liked once I learn it’s that it starts talking about code right away.

When you’re programming, you’re working with objects all the time; so to make your code readable, you need to use proper names for your variables. That’s the first chapter, and that is usually ignored so I was pleased to see that. There’s no right or incorrect method to teach programming, but one specificity is that I don’t really get into code earlier than chapter four. I focus on getting the reader to understand what computer science is, and getting their head around that mind-set about issues.
