This book is written as a follow up to Let’s Go, and we’ll leverage a lot of the information and code patterns from that book again here.
If you’ve already read and enjoyed Let’s Go, then this book should be a good fit for you and the ideal next step in your learning. If you haven’t, then I highly recommend starting with Let’s Go first — especially if you’re a newcomer to Go.
You can read this as a standalone book, but please be aware that it is somewhat advanced — it doesn’t explain the fundamentals in detail, and some topics (like testing) don’t feature at all because they were covered heavily in the previous book. But if you’re comfortable using Go and already have a decent amount of experience behind you, then this book may also be a good fit for you. Feel free to jump straight in.
