"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

Muhimen • May 2 '20

Didn't see that coming

Anurag Hazra • May 2 '20

Yeah because it's "nothing" 😏

Gracrys • May 1 '20

Haskell one is wrong

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

Haskell would be Main = print "Hello world"

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

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)

Awesome!!!

Heres a project I've done, 16 implements of Conways game of life: github.com/KieranP/Game-Of-Life-Im...

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!

Loralighte • May 2 '20

Fair Enough

See this repo
(there is nothing wrong with reinventing the wheel... ;-))

Muhimen • May 2 '20

I thought I was the first person to do this. But you know, there is at least one person on the internet who has done something before you would do.
(But still, I enjoyed it)

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")

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.

Lud • May 4 '20

What about SmallTalk then^^?

Transcript show: 'Hello, world!'.

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
