'''Rosetta Code''' is a [[wiki]]-based programming [[chrestomathy]] website with implementations of common [[algorithms]] and solutions to various [[computer programming|programming]] problems in many different [[programming languages]].<ref>Ralf Lämmel.

==Website==

Rosetta Code was created in 2007 by Michael Mol.<ref name="RCA"></ref> The site's content is licensed under the [[GNU Free Documentation License]] 1.2, though some components may be dual-licensed under more permissive terms.<ref>{{cite web|url=http://rosettacode.org/wiki/Rosetta_Code:Copyrights|title=Rosetta Code:Copyrights|accessdatedate=24 January 2010 |access-date=2010-12-19}}</ref>

The Rosetta Code web repository illustrates how desired functionality is implemented very differently in various [[Programming_paradigm|programming paradigms]],<ref>Neil Walkinshaw. Chapter One: "Reverse-Engineering Software Behavior". [https://books.google.com/books?id=zvNvk-1OuBoC "Advances in Computers"]. 2013. p. 14.</ref><ref>Geoff Cox. [https://books.google.com/books?id=wgnSUL0zh5gC "Speaking Code: Coding as Aesthetic and Political Expression"]. MIT Press, 2013. p. 6.</ref> and how "the same" task is accomplished in different programming languages.<ref>Nick Montfort [http://tropetank.mit.edu/TROPE-13-03.pdf "No Code: Null Programs"]. 2013. p. 10.</ref>

{{As of|2024|02|22}}, Rosetta Code has:<ref>{{cite web|url=http://rosettacode.org/wiki/Welcome_to_Rosetta_Code|accessdateaccess-date=2007-01-07|title=Welcome to Rosetta Code}}</ref>

* 1,266 computer programming tasks (or problems)

* 404 additional draft programming tasks

* 933 computer programming languages that are used to solve tasks

In August 2022, Rosetta Code migrated from independent hosting to [[Miraheze]].

Presently, Rosetta Code is hosted by WikiTide.<ref name="WikiTide">{{Cite web|url=https://meta.wikitide.org/wiki/Special:MyLanguage/WikiTide|title=WikiTide|website=wikitide.org|accessdate=2024-02-22}}</ref>

===Data and structure===

The Rosetta Code site is organized as a browsable cross-section of tasks (specific programming problems or considerations) and computer programming languages.<ref name="ieee"></ref> A task's page displays visitor-contributed solutions in various computer languages, allowing a viewer to compare each language's approach to the task's stated problem.

Task pages are included in per-language listings based on the languages of provided solutions; a task with a solution in the [[C (programming language)|C]] programming language will appear in the listing for C. If the same task has a solution in [[Ruby (programming language)|Ruby]], the task will appear in the listing for Ruby as well.

===Languages===

Some of the computer programming languages found on Rosetta Code (which have Wikipedia descriptions) include: <ref>{{cite web|url=https://rosettacode.org/wiki/Special:MostLinkedCategories?limit=500|accessdateaccess-date=2024-02-22|title=Most linked-to categories}}</ref>
