Go is simple to install. You can install it on a Mac with
brew install go
I’m on Arch Linux and go is available in the main repositories. Packages are available for most Linux distros and you can always compile from source if you want.
pacman -S go
On Windows there is an .msi installer.
After you’ve installed go you can get some help with
go help
As with every programming language you’ll want to run a hello world. Create a file ‘hello-world.go’ and add the code below.
package main
import "fmt"
func main() {
fmt.Println("Hello World")
}
You can run the code with
go run hello-world.go
You can also build your hello world program into a binary
go build hello-world
You can now run the compiled code with
./hello-world
Now time to start learning!
