So... uh... this is a bit embarrassing. But we don't have a plain "Hello, World!" challenge yet (despite having 35 variants tagged with , and counting). While this is not the most interesting code golf in the common languages, finding the shortest solution in certain esolangs can be a serious challenge. For instance, to my knowledge it is not known whether the shortest possible Brainfuck solution has been found yet.

Furthermore, while all of Wikipedia (the Wikipedia entry has been deleted but there is a copy at archive.org ), esolangs and Rosetta Code have lists of "Hello, World!" programs, none of these are interested in having the shortest for each language (there is also this GitHub repository). If we want to be a significant site in the code golf community, I think we should try and create the ultimate catalogue of shortest "Hello, World!" programs (similar to how our basic quine challenge contains some of the shortest known quines in various languages). So let's do this!

The Rules

  • Each submission must be a full program.
  • The program must take no input, and print Hello, World! to STDOUT (this exact byte stream, including capitalization and punctuation) plus an optional trailing newline, and nothing else.
  • The program must not write anything to STDERR.
  • If anyone wants to abuse this by creating a language where the empty program prints Hello, World!, then congrats, they just paved the way for a very boring answer.

    Note that there must be an interpreter so the submission can be tested. It is allowed (and even encouraged) to write this interpreter yourself for a previously unimplemented language.

  • Submissions are scored in bytes, in an appropriate (pre-existing) encoding, usually (but not necessarily) UTF-8. Some languages, like Folders, are a bit tricky to score - if in doubt, please ask on Meta.
  • This is not about finding the language with the shortest "Hello, World!" program. This is about finding the shortest "Hello, World!" program in every language. Therefore, I will not mark any answer as "accepted".
  • If your language of choice is a trivial variant of another (potentially more popular) language which already has an answer (think BASIC or SQL dialects, Unix shells or trivial Brainfuck-derivatives like Alphuck), consider adding a note to the existing answer that the same or a very similar solution is also the shortest in the other language.

As a side note, please don't downvote boring (but valid) answers in languages where there is not much to golf - these are still useful to this question as it tries to compile a catalogue as complete as possible. However, do primarily upvote answers in languages where the authors actually had to put effort into golfing the code.

For inspiration, check the Hello World Collection.

The Catalogue

The Stack Snippet at the bottom of this post generates the catalogue from the answers a) as a list of shortest solution per language and b) as an overall leaderboard.

To make sure that your answer shows up, please start your answer with a headline, using the following Markdown template:

## Language Name, N bytes

where N is the size of your submission. If you improve your score, you can keep old scores in the headline, by striking them through. For instance:

## Ruby, <s>104</s> <s>101</s> 96 bytes

If there you want to include multiple numbers in your header (e.g. because your score is the sum of two files or you want to list interpreter flag penalties separately), make sure that the actual score is the last number in the header:

## Perl, 43 + 2 (-p flag) = 45 bytes

You can also make the language name a link which will then show up in the snippet:

## [><>](https://esolangs.org/wiki/Fish), 121 bytes

Source Engine Console, 18 bytes

echo Hello, World!

You can't try it online unless Valve ports Half-Life 2 to WASM or something.

This script is pretty basic. It's perfectly valid to echo like this without quotes in the Source Engine.

The Source Engine is a game engine developed by Valve Software, and used in all their games after 2004 (until DOTA 2 in 2015). It provides basic scripting through console commands. You can test this by opening the developer console (enable in settings and press the ` key) and pasting the line.

Tested in Team Fortress 2, CS:GO and Source SDK Base 2013 (Multiplayer).

By inspecting some leftover E3 demo scripts in Half-Life 2, it's revealed there was a rem command which could be a shorter 17 bytes, but this is no longer present in the engine (and I assume that a rem doesn't count because it doesn't print anything). I've yet to test if it exists in Source 2004, but can confirm it's missing in Source 2013.

Technically, the console isn't STDOUT, however the only way to really output to STDOUT is by using the SDK to make a game of my own (obviously compiling to a very large size).

Try it online! (heh, line wrapping makes it look wierd)

Automatically generated by this program, with some golfing (manual + golf.rb).

It is very hard to program in 1L_a, so I use generator. Generator creates cells, each cell prints one bit. It iterates through all possible cells with height 6 and no more than 5 inner asterisks to find a cell that prints the needed bit. Generator fails if height is less than 6 or max asterisk count is less than 5.

This is an ungolfed version with cells visible (13*8 = 104 cells):

All of these answers are pretty boring (one is a built-in and the string compression algorithm isn't even my own); consider upvoting some cool answers in tarpits / esolangs rather than this one. I'm just putting it here to have yuno officially be a language on CGCC, and because Hello, World! is a good entry point for any language.

yuno, 1 byte

Try it online!

By default, if the k-literal digraph finds no character after it, it just uses H, because I haven't thought of a good behavior for it otherwise so I may as well save bytes on Hello World.

yuno, 2 bytes

ᴋH

Try it online! Uses the built-in string nilad digraph (inspired by Vyxal).

yuno, 8 bytes

“3ԸaϨ;ψ»

Try it online! Uses a compressed string with the exact same compression algorithm that Jelly uses.

yuno, 15 bytes

“Hello, World!”

Try it online! A default string. As caird coinheringaahing points out, the trailing can be removed if it occurs at the end of the program.
