There should be fixed and sample tests like below:

• Michael Michael. (only 1 valid last name same as first name, still fits in scope since description does not mention otherwise)

• Michael Burmor Michael Jordan Michael Justin Michael Jackson Michael Phisher (a sentence consisting of only all valid names)

This kata is a subject to deduplication process here: https://github.com/codewars/content-issues/issues/195.

It wasn't very clear how to get the current year from the description. Maybe this could be explained?

JS: Node v12 should be used enabled along with its appropiate assertion tools (Mocha + Chai).

JS: No random tests

I think it's better to specify the exact age range of teens in the description. It can mean differently from one place to another.

Cambridge Dictionary defines "Teens" as individuals in the 13-19 years age group.
https://dictionary.cambridge.org/dictionary/english/teens

WHO defines 'Adolescents' as individuals in the 10-19 years age group
https://www.who.int/southeastasia/health-topics/adolescent-health

Some might argue that adolscents is different to teens, but some other might argue otherwise. In the end, it's ambigious.

Groovy translation kumited! Please review and approve. Regards, suic

Python translation

I made a C# translation for this Kata.

I started using a list of dictionaries to store the developers but the code was getting messy so I switched to a list of structs. The struct is declared in the preloaded file.

Suggestions are appreciated.

Description should be language specific, for example for Python the first line "You will be given an array of objects" should be "You will be given a list of dictionaries"

The kata has an unnecessary optimization tag.
