Kata (programming)

Kata (programming) - Wikipedia, the free encyclopedia:
"Code Kata is a term 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. A code kata is an exercise in programming which helps a programmer hone their skills through practice and repetition. As of October 2011, Dave Thomas has published 21 different katas."

Kata (型 or 形 literally: "form")
By practicing in a repetitive manner the learner develops the ability to execute those techniques and movements in a natural, reflex-like manner. Systematic practice does not mean permanently rigid. The goal is to internalize the movements and techniques of a kata so they can be executed and adapted under different circumstances, without thought or hesitation. A novice’s actions will look uneven and difficult, while a master’s appear simple and smooth.
