Rosetta Code is a wiki-based programming chrestomathy website with implementations of common algorithms and solutions to various programming problems in many different programming languages. It was created in 2007 by Mike Mol.
- 882 programming tasks (or problems),
- 223 additional draft programming tasks,
- 676 programming languages,
- 59,711 programming language examples/entries.
The Rosetta Code web repository illustrates how desired functionality is implemented very differently in various programming paradigms, and how "the same" task is accomplished in different programming languages.
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. 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 will appear in the listing for C. If the same task has a solution in Ruby, the task will appear in the listing for Ruby as well.
