Review Quotes

"This book is one any Golang developer will want on their bookshelf. Far from being dogmatic or prescriptive, it often provides multiple solutions to the reader, leaving some room for flexibility and individual taste." Thad Meyer
"Goes beyond the basics with lots of good examples for when concepts are tough to grasp. As someone who's been coding Go for about 2 years, I learned new things." Matt Welke
"This book felt catered to me. I'm not a developer by career path, however it provides a LOT of insight into what I should be thinking about as someone without any education or formal training in Software Development. Really, really nice." Francis J. Setash
"This book not only points out common mistakes and anti-patterns, it provides solutions--a perfect combination for deeper learning." Kevin Liao
"Read this, it'll give you years of experience of Go just learning from the book. Very valuable!" Keith Kim
