Review Summary

Your implementation successfully meets all requirements. The sort2 method correctly sorts arrays in place using bubble sort without invoking the built-in Array.prototype.sort, properly handles both default string comparison and custom compare functions, and returns the original array reference as expected. All checklist items pass. One minor optimization opportunity was noted: the bubble sort performs some unnecessary iterations after the array becomes sorted (it compares adjacent pairs that are already in their final positions). While this doesn't affect correctness and is acceptable per task guidelines, you might consider adding an early termination flag to improve efficiency in future iterations. Great work on implementing the custom sorting logic while respecting the constraint of not using the built-in sort method.
