The “Simple” Hello World

Every programming tutorial starts with “Hello, World!” It’s supposed to be trivial. But comparing Go and Rust versions reveals fundamental philosophical differences.

Go’s Hello World

main.go:

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

Compile and run:

go run main.go

Output:

Hello, World!

Done. Five lines. Zero surprises.
