Hello World!

Let's start with popular programmer style!
As a Java Developer:

class Main {
  public static void main(String[] args) {
    System.out.println("Hello world!");
  }
}
As a C++ Programmer:

#include <iostream>
using namespace std;

int main() 
{
    cout << "Hello, World!";
    return 0;
}
As a Python Developer:

print 'hello world!'
As a fan of Rust:

fn main() {
    println!("Hello World!");
}
As a fan of Go:

package main

import "fmt"

func main() {
 fmt.Println("Hello World!")
}
As a fan of Elixir:

IO.puts "Hello, World!"
