Review Summary

I am approving your solution because it fully meets the task requirements and correctly implements Array.prototype.sort2 without altering the native sort method. You define sort2 via [].__proto__.sort2 = function(compareFunction) { ... } inside applyCustomSort, which matches the required pattern. The sort logic operates in place by swapping this[i] and this[i + 1], and the function returns this, so callers get back the original array reference as specified. When no comparator is provided, you correctly fall back to lexicographical comparison using String(this[i]), which covers cases like numeric arrays that should be sorted as strings. When a comparator is provided, you only swap when its result is greater than 0, which aligns with the standard negative/positive compare contract and should behave as expected across the tests.

A possible minor improvement (not required for this task) would be to factor out the comparison logic into a single helper inside sort2, so you avoid duplicating the two branches for default vs. custom comparison. Overall, your code is clear, readable, and satisfies all checklist items for this assignment—well done.
