This is not a proper way to raise an issue. Consecutive spaces don't display properly in markdown, we don't know what you are refering to. If the map argument annoys you, you just can give it another name. However, there is no reason a parameter could not be named map in Javascript, there is no ambiguity possible with Array.prototype.map if that's your idea (however we cannot know since you don't say it). Please read carefully the documentation and try to follow a minimal quality at the time of posting issues if you hope somebody is able to fix them someday: https://docs.codewars.com/training/troubleshooting/
