I noticed that the "duplicates" test in arrays had only pairs of duplicates, which let me get away with using a pair of nested for loops. I added another "3" to the test array to prompt people to think about other ways to do this.
This test still passes with your answer in js-assessment-answers so there's no pull request necessary over there.
Thanks again! Have a great weekend.
Add a value to the arrays duplicates test array.
The test array had only pairs of duplicates, now it has a triplet of 3s.
This is a great addition, thank you!
