Review Summary

Your solution is approved because it correctly implements makeCalculator with all required methods (add, subtract, multiply, divide, reset, operate) and an initial result of 0, and it supports method chaining via operate and reset. The arithmetic methods are properly shaped to be used as callbacks by operate, and operate correctly updates result based on the callback, matching the task’s functional requirements. There are no violations of the explicit checklist items: naming is appropriate, method shorthand is used, and there are no problematic update patterns like a = a + 2 where they’re disallowed.

One design point to be aware of is how your divide method behaves when dividing by zero; the current choice (e.g., returning 0) may or may not match the tests’ expectations, so if you encounter failing tests around division, revisit that behavior. As a minor robustness improvement, you could also add a typeof callback === 'function' guard in operate to provide clearer errors when misused, though this is not required by the spec. Overall, the implementation is clean, concise, and meets the core requirements—nice work.
