Probably because I was just getting into golang and following a tutorial which did not mention using go run, but I will now thanks :)

Awesome I will give that a try :)

Okay so what I think your saying is if i do something like this as the compilation command

go build main.go && ./main

Then when I run compilation again it will kill the buffer and running process and all will be good ?

I did wonder if that’s perhaps the solution, although not sure how you would get the pid in a make file to kill the running instance, make files are not something I have played with much, I will see if others have any suggestions.
