"Hello, World!" but in 30 different languages!!!

#python #javascript #kotlin #go

Since the last week, I was scratching my head to figure out what post can I write in dev? I wanted it to be meaningful so that it can be useful for the readers. Then, I thought, if I can't write anything meaningful then I should write something absolutely meaningless. And here I am. Printing "Hello, World!" in 30 different languages(in no particular order). ENJOY!

[Spoiler alert: The last one is special!]

1. C

#include <stdio.h>
int main(void){
    printf("Hello, world!\n");
    return 0;
}

2. C++

#include <iostream>
int main(){
 std::cout << "Hello, World!\n";
}

3. C'#'

class HelloWorldApp{
 static void Main(){
 System.Console.WriteLine("Hello, world!");
 }
}

4. Python

print("Hello, world!")

5. Java

public class HelloWorld
   {
        public static void main(String[] args)
        {
             System.out.println("Hello, world!");
        }
   }

6. JavaScript

document.writeln('Hello, World!');

7. TypeScript

console.log("Hello, World!");

8. R

cat("Hello, World!")

9. Rust

fn main() {
    println!("Hello, World!");
}

10. Go Lang

package main 
func main() { 
    println("Hello, World!") 
}

11. Lua

print("Hello, World")

12. Perl

use strict; 
use warnings; 

print("Hello, World!");

13. Haskell

putStrLn "Hello world"

14. Bash

echo 'Hello, world!'

15. Kotlin

fun main() {
    println("Hello, World!")
}

16. Ruby

puts "Hello, World!"

18. Swift

import Swift
print("Hello, World!")

19. Julia

println("Hello, World!")

20. Dart

void main() {
  print('Hello, World!');
}

21. Elixir

IO.puts("Hello, World!")

22. Groovy

println "Hello, World!"

23. Scala

object dev
{
    // Main Method 
    def main(args: Array[String]) 
    {
        // prints Hello World
        println("Hello, World!") 
    }
}

24. Ada

with Ada.Text_IO;
procedure Hello is
begin
   Ada.Text_IO.Put_Line("Hello, world!");
end Hello;

25. Bosque

namespace NSMain;  
entrypoint  
function main(): String {  
 return "Hello, world!";  
}

26. BASIC

PRINT "Hello, world!"

27. Cobol

display "Hello, world!".

28. D

import std.stdio;
void main()
{
    writeln("Hello, World!");
}

29. F'#'

open System
[<EntryPoint>]
let main argv =
    printfn "Hello, World!"

What about "Chicken"?
Chicken is an esoteric programming language in which "chicken" is the only valid symbol.

Here is Hello World in chicken and It's true:

SERIOUSLY?!

Habdul Hazeez • May 2 '20

I thought the same!

JoelBonetR 🥇 • May 5 '20

And what about Cow, intercal, whitespace, chef, Brainfuck or Malbolge?

It seems that bored people has no limits LoL

David Wickes • May 2 '20

Thirty languages, and not a single Lisp? For shame. Three off the top of my head:

Scheme

(display "Hello, world")

Common Lisp

(princ "Hello, world")

Clojure

(print "Hello, world")

Lud • May 4 '20

What about SmallTalk then^^?

Transcript show: 'Hello, world!'.

Muhimen • May 2 '20

My lord! I beg pardon! 🥺

Mohammed Ismail Ansari • May 4 '20

That was the first thing I looked and didn't find.

Heres Hello world in Whitespace:

edit: sadly I think dev.to's markdown based posts & commends doesn't like whitespace-lang

Muhimen • May 5 '20

Who said Java is a hard language to learn?

Samuele Zanca • May 19 '20

Java is quite easy xD

NexWebSites • May 4 '20

;Don't forget Assembly Language:
section .text
global _start

_start:

mov edx, len

mov ecx, msg

mov ebx, 1

mov eax, 4

int 0x80

mov eax, 1

int 0x80

section .data
msg db 'Hello, world!',0xa
len equ $ - msg

James McPherson • May 4 '20

For completeness one should mention that this example is x86 assembler (not even amd64!), and for extra credit how about ARMv7, SPARC and POWER versions too? :p

NexWebSites • May 4 '20 • Edited

Yes, thought it would be better to start with the basics.

global _start
section .text
_start:
mov rdi,1

mov rsi,hello_world

mov rdx,hello_world_size

mov rax,1

syscall
mov rdi,0

mov rax,60

syscall

hello_world: db "Hello, world!",10
hello_world_size EQU $ - hello_world

NexWebSites • May 5 '20 • Edited

How about one for Windows 64?

extrn ExitProcess: PROC
extrn MessageBoxA: PROC

.data
caption db 'Windows 64-bit hello!', 0
message db 'Hello, world!', 0

.code

Start PROC
sub rsp,28h

mov rcx, 0

lea rdx, message
lea r8, caption
mov r9d, 0

call MessageBoxA
mov ecx, eax

call ExitProcess
Start ENDP
End

Hello @muhimen123 , in Go(lang) you can reduce the loc. import "fmt" is not required, you could just use the print/println as you do with the rest of the hello-worlds. You can replace the code snippet with:

package main 
func main() { 
    println("Hello, World!") 
}

Good article though :) It was fun, reminds me old times

Muhimen • May 2 '20

Thanks. Changing the code right now!

Oliver Leaver-Smith • May 5 '20

@muhimen123 you need to change the fmt.Println line to just println, as you are still trying to use fmt, but not importing it any more

Muhimen • May 5 '20

Something like this?

package main 
func main() { 
    println("Hello, World!") 
}

Oliver Leaver-Smith • May 5 '20

Yep, perfect

Peter Gloor • May 5 '20

But remember, according to the documentation print() and println() are built-in functions for bootstrapping and not guaranteed to stay in the language.

Oliver Leaver-Smith • May 5 '20

Yes you are correct. If we want to be pedantic I would say the original post, which had import "fmt" in and used fmt.Println is better than println() but this post seems to be an exercise in "Hello, World! Code Golf" so not too fussed about it

Loralighte • May 2 '20

Although I love this, my Fibonacci Project that I worked on with several other people to get currently 60 languages, I also made sure for more fair comparisons to keep them roughly the same. 60 was a lot too lol.

Muhimen • May 2 '20

Frankly speaking, when I first thought about this post I wanted to write 100 languages. But due to my SUPER procrastinations, I wasn't getting any progress after 30 languages. So I just hit the publish button!

Shakespeare

The Infamous Hello World Program.

Romeo, a young man with a remarkable patience.
Juliet, a likewise young woman of remarkable grace.
Ophelia, a remarkable woman much in dispute with Hamlet.
Hamlet, the flatterer of Andersen Insulting A/S.


                    Act I: Hamlet's insults and flattery.

                    Scene I: The insulting of Romeo.

[Enter Hamlet and Romeo]

Hamlet:
 You lying stupid fatherless big smelly half-witted coward!
 You are as stupid as the difference between a handsome rich brave
 hero and thyself! Speak your mind!

 You are as brave as the sum of your fat little stuffed misused dusty
 old rotten codpiece and a beautiful fair warm peaceful sunny summer's
 day. You are as healthy as the difference between the sum of the
 sweetest reddest rose and my father and yourself! Speak your mind!

 You are as cowardly as the sum of yourself and the difference
 between a big mighty proud kingdom and a horse. Speak your mind.

 Speak your mind!

[Exit Romeo]

                    Scene II: The praising of Juliet.

[Enter Juliet]

Hamlet:
 Thou art as sweet as the sum of the sum of Romeo and his horse and his
 black cat! Speak thy mind!

[Exit Juliet]

                    Scene III: The praising of Ophelia.

[Enter Ophelia]

Hamlet:
 Thou art as lovely as the product of a large rural town and my amazing
 bottomless embroidered purse. Speak thy mind!

 Thou art as loving as the product of the bluest clearest sweetest sky
 and the sum of a squirrel and a white horse. Thou art as beautiful as
 the difference between Juliet and thyself. Speak thy mind!

[Exeunt Ophelia and Hamlet]


                    Act II: Behind Hamlet's back.

                    Scene I: Romeo and Juliet's conversation.

[Enter Romeo and Juliet]

Romeo:
 Speak your mind. You are as worried as the sum of yourself and the
 difference between my small smooth hamster and my nose. Speak your
 mind!

Juliet:
 Speak YOUR mind! You are as bad as Hamlet! You are as small as the
 difference between the square of the difference between my little pony
 and your big hairy hound and the cube of your sorry little
 codpiece. Speak your mind!

[Exit Romeo]

                    Scene II: Juliet and Ophelia's conversation.

[Enter Ophelia]

Juliet:
 Thou art as good as the quotient between Romeo and the sum of a small
 furry animal and a leech. Speak your mind!

Ophelia:
 Thou art as disgusting as the quotient between Romeo and twice the
 difference between a mistletoe and an oozing infected blister! Speak
 your mind!

[Exeunt]

Haskell one is wrong

is using the repl. And is not even printing a thing

Haskell would be Main = print "Hello world"

Madeline Trotter • May 4 '20

This isn't valid file or repl syntax.

For the repl:

putStrLn "Hello world"

For a .hs file:

module Main where

main = putStrLn "Hello world"

(function definitions are lower case, types and modules are capitalized)

Craig McIlwrath • May 2 '20

putStrLn would probably be better for this, so it doesn't display the quotes

Muhimen • May 2 '20

Bug in the post 🙄. Fixing it right now!

Madeline Trotter • May 4 '20

I'm not sure what it used to be, but this update isn't right. Here are two valid definitions: dev.to/spicydonuts/comment/ofod

Michael S. Mikowski • May 4 '20 • Edited

Perl doesn't need use strict or use warnings for this trivial example. Why are you making it needlessly verbose? Using the same logic shouldn't we also use set -u and set -e in bash? Btw, fun post. Just trying to be fair.

Luiz "Bills" • May 6 '20 • Edited

PHP

<?= 'Hello, world!' ?>

JASS (language used in Warcraft III mods)

function InitTrig_Main takes nothing returns nothing
    call BJDebugMsg("Hello World")
endfunction
