Review Summary

Your solution is approved because it correctly implements all required calculator features and behaves as specified, including chaining and the final result in the example sequence. makeCalculator returns the right object shape, operate uses the callback appropriately to update result, and both operate and reset return this, so the core functional requirements are fully met.

One minor style issue remains: in src/makeCalculator.js, your multiply and divide methods use this.result = this.result * num; and this.result = this.result / num; instead of the augmented assignment forms this.result *= num; and this.result /= num; as recommended by [CHECKLIST ITEM #2]. This doesn’t break functionality, but aligning these with your existing += and -= usage will make the code more consistent and closer to the checklist guidance. Overall, you met the task’s functional standards well; consider applying that small style improvement as a polish step.

This violates checklist item #2: use arithmetic operators with assignment operator = if you want to add something to existing value. Instead of this.result = this.result * num;, use the *= operator as in the provided good example.

This also violates checklist item #2: use arithmetic operators with assignment operator = if you want to add something to existing value. Instead of this.result = this.result / num;, use the /= operator.
