I like GO because It implements cleanly such modern features as abstract data type, data encapsulation, object composition, interface, package, CSP model (Tony Hoare) concurrent programing, multi-value-return function, deferred function calls, garbage collection, exporting names by capitalization, simple but effective exception handling and memory model. It is a static type language. Higher abstract data types such as map (hash table), string, array and slice are built in to simplify memory management. Its syntax is succinct (only 25 keywords). Yet using it correctly can lead to powerful program constructs. Little redundancies are built into the language. As such, there are not many alternate ways to do one thing which leads to codes that are easy to understand and maintain. The designers deliberately choose to implement features to support object composition instead of inheritance, to handle exception where it happens instead of the throw and catch clauses, to use simple "struct literals" to initialize abstract data type instead of constructor functions, and "type" expression to help users consistently define user types, interface (abstract) type as a standard protocols to call different concrete-objects methods (the correct way to implement polymorphism). It does not have default arithmetic type conversion, and function name overloading, which together with class inheritance (function overwrite), constructor functions, throw-and-catch exception handling are the sources of needlessly programing complexity. Importantly, both procedure (functions and data structures) and object-oriented (objects and methods) methodologies can be used. There are just enough features that help make GO a pleasant language to write. All features are careful designed to work well together which facilitate a program model that is quite powerful, but simple to learn, reason, write, and support.
The book is well written by a GO expert programmer and a computer pioneer and noted author of programing books. Concepts are coherently and timely presented. Examples are usually not code fragments, but complete programs which can be compiled and run. Programs of complex concepts are presented in multiple versions from simpler to more elaborated ones. Like the efficient design of GO, the book is never overwritten. It is the most enjoyable programing book I have read in a long while.

FlexibleGo bears a surface similarity to C and, like C, is a tool for professional programmers, achieving maximum effect with minimum means. But it is much more than an updated version of C. Go borrows and adapts good ideas from many other languages, while avoiding features that have led to complexity and unreliable code. Co-author Brian Kernighan was a co-creator of several programming languages and the co-author of one of the most popular programming books of all-time The C Programming Language. |
General-purpose languageGo is especially well suited for building infrastructure like networked servers, and tools and systems for programmers, but it is truly a general-purpose language and finds use in domains as diverse as graphics, mobile applications, and machine learning. The book features hundreds of interesting and practical examples of well-written Go code that cover the whole language, its most important packages, and a wide range of applications |
EfficientGo programs typically run faster than programs written in dynamic languages and suffer far fewer crashes due to unexpected type errors. This book is meant to help you start using Go effectively right away and to use it well, taking full advantage of Go’s language features and standard libraries to write clear, idiomatic, and efficient programs. |

I found no print issues with my copy as you can see. I have had a few AW blue&white cover books and they have always been really nice.
