While Go is both a great general purpose and low-level systems language, one of its primary strengths is the built-in concurrency model and tools. Many other languages have third-party libraries (or extensions), but inherent concurrency is something unique to modern languages, and it is a core feature of Go's design.

Though there's no doubt that Go excels at concurrency—as we'll see in this book—what it has that many other languages lack is a robust set of tools to test and build concurrent, parallel, and distributed code.

Enough talk about Go's marvelous concurrency features and tools, let's jump in.

Introducing goroutines

The primary method of handling concurrency is through a goroutine. Admittedly, ...
