Hello World in Every Language

What originally started as a 100 Days of Code challenge has blossomed into a serious project. Welcome to Hello World in Every Language: a series of Hello World implementations in as many programming languages as possible.

What is Hello World?

According to Wikipedia, Hello World is any program that displays “Hello, World!” to the user. In many cases, Hello World is used to demonstrate basic features of a programming language.

The Hello World program supposedly first appeared in 1972 in Brian Kernighan’s book A Tutorial Introduction to the Language B:

main(){
  extrn a,b,c;
  putchar(a); putchar(b); putchar(c); putchar('!*n');
  }

a 'hell';
b 'o, w';
c 'orld';

Today, Hello World has become the standard introduction to just about every programming tutorial. In fact, I even used Hello World in my Java class structure tutorial. Now, I’m trying to implement Hello World in every programming language.

Why Hello World in Every Language?

Now to be fair, I’m not the first person to tackle Hello World in every language. In fact, there are two archives I’m aware of:

1. The Hello World Collection
2. The leachim6 GitHub Repo

Both of these archives simply list the various Hello World implementations without a lot of context. As a result, these archives are much larger than my GitHub collection.

However, if you’re looking for something a bit more interesting, you’re in luck. With each of my implementations, you’ll get a brief breakdown of the solution and the historical background of the language. As a bonus, you’ll get to watch me grow on this journey. Hopefully, that’s a little more fun!

An Alphabetical List of Languages

If you’ve had a chance to browse through any of my Hello World implementations, then you know that there’s really no order in the chaos. In other words, I explore languages almost randomly. While that’s fun for me, I am certain this is frustrating to you.

As a result, I’ve decided to provide a list of all the languages in alphabetical order. Consider this an index:

1. Hello World in ALGOL 68
2. Hello World in Bash
3. Hello World in Befunge
4. Hello World in Brainfuck
