Review Summary

Your implementation of Array.prototype.sort2 in src/arrayMethodSort.js is approved because it satisfies the core requirements: it sorts the array in place, returns the original array (this), uses string-based comparison when no compareFunction is provided, and correctly delegates ordering to a user-supplied compareFunction without ever calling the built-in Array.prototype.sort [CHECKLIST ITEM #1, #3, #4, #5, #6]. The bubble-sort style nested loops you used constitute a valid custom sorting algorithm and will work correctly for the test inputs described in the task. As a minor clean-up, you can simplify the inner loop by removing the temporary shouldSwap flag and swapping elements directly inside the if where you decide the order, which will make the code easier to read. Another optional improvement is to limit the inner loop to this.length - i - 1 so you avoid re-checking the already sorted tail portion of the array during later passes. For extra robustness (not required by the checklist), you could guard compareFunction with typeof compareFunction === 'function' so that passing non-function values falls back to the default string comparison instead of throwing. Overall, this is a solid solution that meets the task’s functional requirements and demonstrates a good understanding of how custom sort logic works.
