Coding Dojo: Tell, Don't Ask Kata

We will be working on the Tell Don't Ask kata by Gabriele Tondi. It is a fantastic case of refactoring based on enforcing the "Tell, Don't Ask" principle (https://martinfowler.com/bliki/TellDontAsk.html) in an existing codebase with an anemic domain model*

Please, find the starting code here:

• Original (Java): https://github.com/gabrieletondi/tell-dont-ask-kata
• Translation to Python and Typescript (thanks Eduard Maura!): https://github.com/mapu77/tell-dont-ask-kata

*Check the README file in the repo for more details on how to approach the kata!
