We describe serial vs concurrent execution. GO has powerful facilities for concurrent programming. For example, in any language (including GO) we can serially execute two routines:
routine1(…)
routine2(…)
This would cause routine1 to be executed to completion before routine2 is started.
However, in GO, we can also use the following construct:
go routine1(…)
go routine2(…)
Here routine1 and routine2 are goroutines that run concurrently.
