Review Summary
Decision: APPROVE
Your implementation and tests meet the core requirements. There are no critical blockers: the function behaves correctly, tests are valid, and the ESLint config is functional. Nice work keeping the algorithm simple, pure, and producing an ascending split with max–min ≤ 1.
Minor improvement (non-blocking): in .eslintrc.js, on the line where no-proto is disabled (likely near the rules section), prefer the named severity ("no-proto": "off") or add a short comment explaining why __proto__ usage is allowed. This makes intent clearer for future maintainers. Optionally, expand the test suite with a case like splitInteger(17, 4) -> [4,4,4,5] and a property-style test asserting length, integerness, and max - min <= 1 to strengthen coverage.
Overall, solid job—requirements are fully met.

The configuration disables the no-proto rule using a numeric severity (0). Consider one of the following for clarity:
- Use the named severity:
"no-proto": "off"so it's immediately clear to readers, or - Add a brief comment explaining why you disabled this rule (e.g., legacy code relies on
__proto__).
Either approach improves maintainability but is not required for functionality.

Review Summary
Decision: Requesting changes because key checklist requirements for tests are missing.
Critical issues to fix (blockers):
- src/splitInteger.test.js: Missing required example test for
splitInteger(17, 4)→ must assert[4, 4, 4, 5](task explicitly lists this example). - src/splitInteger.test.js: Lacks property-based assertions that the checklist requires across scenarios. Please add tests that verify for representative inputs:
- length equals
numberOfParts(e.g.,expect(result).toHaveLength(numberOfParts)), - sum equals
value(e.g.,expect(result.reduce((a,b)=>a+b,0)).toBe(value)), - sorted ascending (check each
result[i] <= result[i+1]), max - min <= 1(e.g.,result[result.length - 1] - result[0] <= 1).
Include at least: a divisible case, a non-divisible case,numberOfParts = 1, andvalue < numberOfParts(you can reuse your existing values and add these property checks to them).
- length equals
Minor (non-blocking) improvements:
- .eslintrc.js: Prefer
'no-proto': 'off'over0, and add a short comment if disabling is intentional for readability.
Your implementation looks solid; once the missing example and property tests are added, this should meet the checklist. Keep the current example-based tests and supplement them with the property checks.

Consider using the string form for the rule level for readability and adding a short justification comment if disabling no-proto is intentional. For example:
'no-proto': 'off' // disabled to allow use of __proto__ in test helpers / legacy interopUsing 'off' is clearer than 0 and helps future maintainers understand the intent.

This test asserting exact equality for splitInteger(6, 2) is fine for the example. In addition, add a property-based test (for divisible case) that checks: - the returned array has length numberOfParts, - the sum equals value, - array is sorted ascending, - max - min <= 1. That ensures the core constraints are validated independently of exact distribution.

Good: this test covers the numberOfParts = 1 case. Consider also adding a property test for this scenario that asserts length and sum explicitly (e.g., expect(result).toHaveLength(1); expect(result.reduce((a,b)=>a+b,0)).toBe(8);).

This example-based test for splitInteger(32, 6) is fine, but the task checklist requires a test for the example splitInteger(17, 4) which is missing. Add a test asserting splitInteger(17, 4) yields [4, 4, 4, 5]. Also add a non-divisible property-based test (could use 32,6 or 17,4) that checks length, sum, sorted order, and max - min <= 1 rather than relying only on exact equality.

This test covers the value < numberOfParts case and asserts a concrete expected array. Also add a property-based test for this scenario verifying length and sum (and the max-min <= 1 constraint). That will satisfy checklist items requiring varied scenario coverage without over-constraining internal distributions.
