Another example of "Hello World" style programs is FizzBuzz. This is one example of a FizzBuzz implementation. Very idiomatic Go in play here.
package main
// Simple fizzbuzz implementation
import "fmt"
func main() {
for i := 1; i <= 100; i++ {
s := ""
if i % 3 == 0 {
s += "Fizz"
}
if i % 5 == 0 {
s += "Buzz"
}
if s != "" {
fmt.Println(s)
} else {
fmt.Println(i)
}
}
}
