welcome
Thanks for purchasing the MEAP for Go by Example: Programmer's guide to idiomatic and testable code. Well-designed code in Go demands a different mindset, and if you want to write Go code that's easy to test and maintain, you've come to the right place!
To get the most benefit from this book, you'll need to be a programmer, at least with an intermediate knowledge of any programming language. You may be new to Go, but knowing the basics will help along the way. If you don't know the basics of the Go programming language, you can learn it through my open-source repository that contains 1000+ explanations and exercises.
When I first started experimenting with Go five years ago, it was out of necessity. I needed a modern and simple programming language. Since that time, there have been numerous examples, some really great introductions to the language, and a few cookbooks to help newcomers learn the basics. As I write this, there's no book yet on writing and structuring practical and testable code in Go, but there's a growing need for developers. Go by Example is my attempt to write and maintain practical and testable code using Go.
Go is relatively a young language, and hundreds of thousands of developers from other programming languages come to Go every year. If you're one of them, you may be wondering how to transfer your existing knowledge of other languages, particularly when it comes to writing idiomatic and testable code in Go.
