Starting with the foundational principles, such as syntax, and scaling up to advanced topics such as big data analysis, this book will give you all of the tools you need to be a professional Ruby developer. A few of the key topics object-oriented programming, built-in Ruby methods, core programming skills, and an introduction to the Ruby on Rails and Sinatra web frameworks. You will also build 10 practical Ruby programs. Created by an experienced Ruby developer, this book has been written to ensure it focuses on the skills you will need to be a professional Ruby developer. After you have read this book, you will be ready to start building real-world Ruby projects.
This book has too much emphasis on gimmicky tools for a true guide. It also includes glaring factual errors like a blanket recommendation for floating point types over integral types due to "superior precision" without discussing round-off error, and a belief that all APIs use string types requiring coercion. I found the free Programming Ruby guide on the Ruby Doc website to be far better written.
