Rosetta Code

From Rosetta Code
(Redirected from Main Page)

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 868 tasks, 203 draft tasks, and is aware of 675 languages, though we do not (and cannot) have solutions to every task in every language.
