Hello Foo - Println

In go you can use the := operator to declare a variable and assign a value to it at the same time. Then you can use that variable in a Println. As you might notice, (I did not when I first tried this), the `Println function inserts a space between the values it prints. For better control about this you can use Printf.

package main

import (
func main() {
    name := "Foo"
    fmt.Println("Hello", name)

Hello Foo
