This is my Kata WIP page.
A code kata is an exercise in programming which helps a programmer hone their skills through practice and repetition. The term was probably first coined by Dave Thomas, co-author of the book The Pragmatic Programmer, in a bow to the Japanese concept of kata in the martial arts.
You can use kata to test a new workflow, try new shortcuts on your IDE or examine new patterns. Mostly you code and when finished delete the code and try again a different way.
