I am currently playing with Google Go language.
Learn more about it at www.golang.org
It is a pretty fast language to build efficient things. I work on my MAC OSX and love that.

My first HelloWord.go code is available on my GitHub repo here.
It is almost empty as what I was trying to do was mostly understand the setup of Go and push something.
It uses the Println function, which definitions goes as follow:

From my terminal, when typing GO, we can see that the commands are:

build       compile packages and dependencies

clean       remove object files

doc         show documentation for package or symbol

env         print Go environment information

fix         run go tool fix on packages

fmt         run gofmt on package sources

generate    generate Go files by processing source

get         download and install packages and dependencies

install     compile and install packages and dependencies

list        list packages

run         compile and run Go program

test        test packages

tool        run specified go tool

version     print Go version

vet         run go tool vet on packages

Use “go help [command]” for more information about a command.

Let see where I get with it after couple of days.
