COBOL translation.

If the input array is empty or null, return an empty array.

if the number of positives = 0 (i.e no positive numbers) and sum of negatives = 0 (i.e no negative numbers), there are only two possible input arrays:

1. List consisting of zero's only, which has been covered in the example test cases

2. List is empty, which has been covered by

If the input array is empty or null, return an empty array

One of the tests seems to expect that if number of positives == 0 and sumOfNegatives == 0 we should return an empty array. That was nowhere in the description and I had to guess that that is what the test wants. Would be nice if you could update description that this is expected.

This explanation from njxue should be added to the description of the kata - the actual description of the Kata is confusing. Thanks nxjue!

Sorry but you are wrong: 6/9 is 2/3 and 60 is divisible by 3.

One of the tests is:

assert.strictEqual(
  convertFrac([[1, 2], [4, 5], [3, 4], [6, 9], [7, 10]]),
  "(30,60)(48,60)(45,60)(40,60)(42,60)"
);

But 60 is not divisible by 9 so the answer should be (90,180)(144,180)(135,180)(120,180)(126,180)

same issue, even though iam outputting with to_char
