Used same approach for names. Thanks for the help.

Thanks, for feedback, I have now changed it to use a Set.

Thanks, fixed, please review.

Thanks, Blind4Basics, fixed the issue and also made my reference function different.

Appreciate the feedback, but I need you to help and elaborate here. The function has one input, an array of votes, and I have tried to prevent this from being mutated, so what else can be modified?

Reduced the number of elements, error message should be more concise now.

The object is no longer repeated.

Randomised name and party.

Can you provide an example, please? Thanks.

I tried to prevent array mutation as follows [...votes] when passing votes into the functions and the output message. Please provide example if this is not correct.

Prevented array mutation between function calls.

Vote count is now unique in test cases.

Test cases expanded to 100.
