It's now time to dig deeper into the clean API that Go provides in order to write concurrent software with ease.
A goroutine is simply defined as a light-weight thread that you can use in your program; it's not a real thread. In Go, when you define a piece of code as a new goroutine, you basically tell the Go runtime that you would like this piece of code to run concurrently with other goroutines.
Every function in Go lives in some goroutine. For example, the main function that we discussed in the previous chapter, which is usually the entry point function for your program, runs on what is known as the main goroutine.
So, how do you create a new goroutine? You just append the go keyword before the function that you would like to run concurrently. The syntax is quite simple:
go somefunction()
Here, somefunction() is the piece of code that you would like to...
