I took three stars off this review because the writing on the binding is upside down and ruins my bookshelf. Fortunately, this book is worth 8 stars if they fix that issue. It'll rock your face off. I won't repeat what others have already mentioned, solid theory, working code, test driven development, fun af, etc. The real beauty of this book is in it's repetition of actually teaching the reader over and over again, in subtle and nuanced ways how to expand the language as you go. The celebration at the end, is well worth it. This book will be transformative in the tech scene and may inadvertently launch a thousand new languages. This is how I ran through it. Two bookmarks. One to mark where I have coded to, the other one for where I am reading ahead to. As I find time, I hop into vscode, use copilot for some auto-complete help, made quick work of the sections, watch the tests blow up, and code to make them work until I arrive at my read to bookmark. Finally, I commit when I've completed adding a feature and repeat this process until the end. My reading time consisted of me reading a chapter or section, and then scrolling through my code on the github app following along on how it all worked. I highly advise keeping the SICP and Nystrom's Crafting Interpreter literature nearby, just to have the additional light bulb moments. This will be money well spent. I didn't spend any, however, as I received this and the compiler one for Christmas '23. Some of the best gifts I've ever been given.
