16. Concurrent Work

Overview

This chapter introduces you to the Go features that will allow you to perform concurrent work, or, in other words, achieve concurrency. The first feature you will learn is called a Goroutine. You'll learn what a Goroutine is and how you can use it to achieve concurrency. Then, you'll learn how to utilize WaitGroups to synchronize the execution of several Goroutines. You will also learn how to implement synchronized and thread-safe changes to variables shared across different Goroutines using atomic changes. To synchronize more complex changes, you will work with mutexes.

Later in the chapter, you will experiment with the functionalities of channels and use message tracking to track the completion of a task.
