Hello, World!

Let's give 👋 to world in some programming languages!

1. JavaScript

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

2. C++

   #include <iostream>
   int main()
   {
     std::cout << "Hello, World!" << std::endl;
     return 0;
   }

3. Python

   print("Hello, World!")

4. Java

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

5. C

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

6. Assembly

   section .data
       hello db 'Hello, World!', 0  ; String will be showed
    
   section .text
       global _start                  ; Start point program
    
   _start:
       mov rax, 1                     ; syscall: write
       mov rdi, 1                     ; file descriptor: stdout
       mov rsi, hello                 ; string address
       mov rdx, 13                    ; string length
       syscall                         ; call kernel
    
       mov rax, 60                    ; syscall: exit
       xor rdi, rdi                   ; exit code: 0
       syscall                         ; call kernel

   I wish this will return 'Hello, World!'.

8. Haskell

   main :: IO ()
   main = putStrLn "Hello, World!"

9. Prolog

   :- initialization(main).
    
   main :- write('Hello, World!'), nl.

10. Rust

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