Loved this kata! Very good and interesting description, clear task and easy to understand solution. I wish there were more katas like this one ^^

Good one with the prototype. but if the object will be created with the class, the prototype is created automatically.

Thank you for having specific and clear description what this Kata asks for. In contrast, I often feel the descriptions of several Kata(s) especially those in OOP tag are often ambiguous, resulting in taking more time for me to figure out what Kata asks for than actually thnking abut the code.

I figured it out, but the long winded description sucked the energy out of me and it took me a rest to get up to speed with the slight mathematical thinking that this kata needs

Forked the JS translation with the only change being using an ES6 class in the setup code instead of a constructor function. Won't break compatibility with any of the constructor function solutions, but might nudge future users into making use of the modern OOP syntax in JS.
