A Coding Dojo is a usually quite simple exercise that is meant to improve your coding skills. The Dojo we will be doing is language agnostic, which means you can solve it in the language of your choice. You don't need to be an expert in that language, but you should have written a function or three.
Bring: A laptop with the language of your choice installed, and an editor/IDE set up, so you can start coding right away. Depending on your language, having an empty project and a library/framework for unit testing prepared can also come in handy.
Bring also: An open mind and the willingness to make mistakes and learn from them!
