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 WikipediaOpens in a new tab., 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:

  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 CollectionOpens in a new tab.
  2. The leachim6 GitHub RepoOpens in a new tab.

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 collectionOpens in a new tab..

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
  5. Hello World in C
  6. Hello World in C*

  43. Hello World in Solidity
  44. Hello World in Swift
  45. Hello World in Visual Basic .NET
  46. Hello World in Wren

As always, thanks for sticking around. If there’s a language missing that you want to see, feel free to drop it down in the comments. I’m always looking to explore new languages.

Sample Programs in Every Language (44 Articles)—Series Navigation

For 100 Days of Code, I’ve decided to implement a few sample programs in as many languages as possible. Each implementation details a brief history of the language and a description of the code.

The plan for the series is to explore the major general-purpose language like Java, Python, C, C++, and C#. From there, we’ll take a look at some sample programs in web development languages like Ruby, PHP, and JavaScript. As we continue, we’ll cover proprietary languages like Swift and Objective-C. Eventually, we’ll start to tackle less popular languages like Rust, x86, and Verilog. Finally, we’ll play around with some of the esoteric languages like Brainf*ck and LOLCODE.

Who knows? Maybe the Sample Programs in Every Language series will become so popular it’ll never end. To help this series grow, consider sharing it on social media with your friends. Or, if you have a language you want to see, drop your suggestion in the comments.
