Mastering concurrency can make you a much more in-demand developer on the job market. It's becoming an increasingly important concept in modern programming as multi-core devices become more and more prevalent.

The good news is that Go has some outstanding support for concurrency out of the box that makes implementation a breeze. In fact, concurrency in Go is easier to implement and faster than in any other major language.

In this course, you'll start off with a general introduction to concurrency and build up to more advanced concepts and implementation in Go. You'll also have a chance to go through some common patterns that will make your life easier and your code more efficient. By the time you're done, you'll be able to make use of Go to write efficient, practical applications that use concurrency.

Mastering Concurrency in Go

In this chapter, we'll look at some concurrency patterns that can come in handy while we write concurrent code. 

Let's begin with generators. Generators return the next value in a sequence each time they are called. This means that each value is available as an output before the generator computes the next value. Hence, this pattern is used to introduce parallelism in our program. 

Have a look at the simple example below:

Let's study our first pattern​ of concurrency, which is about generators that return channels as returning argument.
