Review Summary
Great job covering different scenarios in your tests, especially the edge case where the value is smaller than the number of parts!
I'm requesting a small change to make a couple of your tests more precise. In your first two tests, the assertions only check parts of the returned array, which means they don't fully verify the function's output. For example, expect(result[0]).toEqual(10) doesn't guarantee the array has only one element.
A more robust approach is to check the entire array's structure and content. Could you please update these assertions to use toEqual to check the entire array, like this?
// For the first test
expect(result).toEqual([10]);
// For the second test
expect(result).toEqual([3, 3]);This will ensure your tests fully validate that the function's output matches all requirements, including the correct length and values.

This assertion is a bit weak because it only checks if the first two elements are equal, but it doesn't verify the total number of elements in the array. A more robust approach is to check the entire array's structure and content, for example: expect(result).toEqual([3, 3]);. This ensures the array has the correct length and values.

This assertion only checks the value of the first element. It doesn't guarantee that the array contains exactly one element as required. To make this test more precise, it's better to check the entire array. For instance: expect(result).toEqual([10]);.

Review Summary
Excellent work on these tests! I'm happy to approve this submission. You've done a great job addressing the previous feedback by making the test assertions more specific. The test suite is now robust and covers all the required scenarios, including equal parts, single parts, and unequal distributions. Everything looks correct and meets the task requirements. Well done!
