Now that we have a sense of what Go is capable of and how to test drive some concurrency models, we need to look deeper into Go's most powerful features to understand how to best utilize various concurrent tools and models.
We played with some general and basic goroutines to see how we can run concurrent processes, but we need to see how Go manages scheduling in concurrency before we get to communication between channels.
By this point, you should be well-versed in what goroutines do, but it's worth understanding how they work internally in Go. Go handles concurrency with cooperative scheduling, which, as we mentioned in the previous chapter, is heavily dependent on some form of blocking code.
The most common alternative to cooperative scheduling is preemptive scheduling, wherein each subprocess is granted a space of time to complete and then its execution is paused for the next.
