Nice additional info, but not a kata suggestion :-)

Approved

Lua translation!

Your answer is different from the expected one:

['Open', ' Senior', 'Open', ' Senior'] should equal 
['Open', 'Senior', 'Open', 'Senior']

Usually when tests fail it means that the expected solution is not OK.

Is there a reason why I'm failing the tests despite the expected solution being ok? Maybe I am missing something.

Sorry I meant number[][] / [number, number][]. I changed the type to use shorthand syntax rather than generic types

Array<number> and number[] mean the same thing.

I agree, absolutely no point mentioning that a lower handicap is better, that's what makes this confusing.

Thanks!

A problem with your code is not a kata issue. Use question label next time.

To be a senior, a member must be at least 55 years old and have a handicap greater than 7
