What is Wollok?

Wollok is not only a programming language but also an IDE (Integrated Development Environment) specially designed for teaching initial OOP courses. It is a great tool to incrementally add every OO concept, allowing the students to program from the beginning! This is Wollok Xtext web site, our first official implementation. In July 2024, we'll be releasing a brand new product: wollok-ts!
