"Hello, World!" - Your First Freight Program

Here's a simple "hello world" program in Freight:

import { IO } from "freight"

export package "hello" {
  export function world() {
    IO.print_line("hello world")
  }
}

To run this program, use freight run and specify the location of the function that is to be executed:

$ freight run 'hello::world()'
hello, world!

You can also compile the program to a binary, and run the built binary instead:

$ freight build 'hello::world()' ./hello-world
$ ./hello-world
hello, world!
