Great, we were able to use the Go compiler to build an executable. We can run that executable as many times as we want.
But what happens if we ever wanted to change our program? We would have to compile another executable file and then run that file. Imagine having to do that every single time!
Thankfully, we have the
go run command followed by the name of the Go file. We can use the
go run command like so:
go run greet.go
go run command compiles the code (like
go build) and executes it. Unlike
go run will NOT create an executable file in our current folder.
We provided the same Go file as the previous exercise.
This time, compile and run the
main.go file in a single command.
