class Main {

}

Program Standard Out:

Hello World!

Pretty Printed Program:

class Main { function main(): unit = println("Hello World!")  }

Compiled JS:

const _builtin_stringConcat = (a, b) => a + b;
const _builtin_println = (line) => console.log(line);
const _builtin_stringToInt = (v) => BigInt(v);
const _builtin_intToString = (v) => String(v);
const _builtin_throw = (v) => { throw Error(v); };

const _module_Demo_class_Main_function_main = () => {
  var _t0 = _builtin_println("Hello World!");
};
const _compiled_program_main = () => {
  _module_Demo_class_Main_function_main();
};

_compiled_program_main();
