Review Summary

I am requesting changes because the tests in src/getCoinCombination.test.js do not yet fully satisfy the explicit task requirements. The description calls for dedicated tests for the exact example outputs getCoinCombination(1) === [1, 0, 0, 0] and getCoinCombination(6) === [1, 1, 0, 0] (along with 17 and 50), and currently only 17 and 50 are directly covered. This means checklist items [CHECKLIST ITEM #7] and [CHECKLIST ITEM #8] are not met, which is a blocker for completing the task as specified.

Critical issues to fix:

• Add an it block that calls getCoinCombination(1) and asserts that it returns [1, 0, 0, 0] using a strict equality check like toEqual.
• Add a separate it block that calls getCoinCombination(6) and asserts that it returns [1, 1, 0, 0].

You’ve done a good job already covering other behaviors and ranges, so once you add these explicit example tests, your solution should fully meet the checklist requirements. Keep going—you’re very close to the finish line.

The task description requires explicit tests for the example behaviors, including getCoinCombination(1) === [1, 0, 0, 0] and getCoinCombination(6) === [1, 1, 0, 0]; these specific cases are currently missing, so consider adding dedicated it blocks for cents 1 and 6 to satisfy checklist items #7 and #8.

Review Summary

Your solution is approved because the test suite now fully meets the task requirements and correctly exercises getCoinCombination for all specified example inputs. You have clear Jest tests for 1, 6, 17, and 50 cents, and each expectation matches the required output format [pennies, nickels, dimes, quarters], confirming the interpretation of the returned array. The tests focus only on the src/getCoinCombination.js implementation without modifying it, which respects the constraints of the assignment. You also included a basic sanity check to ensure the function is declared and returns an array, which adds a small but useful layer of robustness.

There are no critical functional gaps or blockers remaining: all checklist items, including the dedicated tests for 1 cent [CHECKLIST ITEM #7] and 6 cents [CHECKLIST ITEM #8], are satisfied. As an optional improvement, you could add one or two more mixed-coin cases (for example, 23 or 41 cents) to further validate combinations beyond the given examples, but this is not required for completion. Overall, this is a solid, focused test file that aligns well with the assignment’s intent—nice work bringing it to completion.
