Rosetta Code is a repository for code examples that go beyond the traditional "Hello World!" example. A series of tasks are listed, and visitors to this site are asked to complete the tasks in the language of their choice. The tasks are intended to cover a variety of needs commonly found in software.

Rosetta Code is a programming chrestomathy site. The idea is to present solutions to the same task in as many different languages as possible, to demonstrate how languages are similar and different, and to aid a person with a grounding in one approach to a problem in learning another. Rosetta Code currently has 1,275 tasks, 401 draft tasks, and is aware of 946 languages, though we do not (and cannot) have solutions to every task in every language.
