Review Summary
Good job setting up the tests and covering several key scenarios for the splitInteger function. However, this requires changes because one of your tests doesn't fully validate a core requirement. The test in src/splitInteger.test.js that checks for ascending order is not robust enough.
As noted in the comment, your current assertion could pass for an unsorted array like [4, 5, 4, 4]. To properly verify the sorting, please update the test to assert against the complete, expected array. For example:
expect(result).toEqual([4, 4, 4, 5]);This single assertion will correctly validate the array's contents, length, and sorted order, ensuring the requirement is fully met.

This assertion is a creative way to check the order, but it doesn't fully verify that the entire array is sorted. For example, if the function returned [4, 5, 4, 4], this test would still pass because the unique ordered values are 4 and 5, but the array itself isn't sorted.
A more reliable way to test this is to compare the result against the complete expected array. For this case, you could assert expect(result).toEqual([4, 4, 4, 5]), which validates the contents, length, and order all at once.

Review Summary
Excellent work on this iteration! You've successfully addressed the feedback from the previous review by making your tests more robust, especially the one checking for ascending order. Your test suite now correctly validates all the specified requirements for the splitInteger function. I am approving your solution, keep up the great work!
