What Makes the Intro to *Crafting Interpreters* so Good?

One of my favorite programming books is Crafting Interpreters by Bob Nystrom. It teaches you how to build a programming language from scratch. Along the way, you learn about text parsing, data structures, virtual machines, and several other skills that make you a stronger developer.

I was re-reading the book recently and realized that its introduction is delightfully effective. Developers are terrible at writing introductions, so it’s worth studying what makes the Crafting Interpreters intro so compelling.
