Review Summary
Great work on this task! Your solution is approved as you've successfully implemented the custom sort2 method on the Array.prototype, and it correctly handles both default and custom comparison functions, meeting all requirements.
While your implementation is fully functional, there's a small optimization you could make to your bubble sort algorithm for better performance. As noted in the comment on src/arrayMethodSort.js, you can adjust the inner loop's condition to j < arr.length - 1 - i. This avoids redundant comparisons with elements that have already been sorted to the end of the array.
This is just a suggestion for future improvement. Excellent job overall!

This implementation of bubble sort is functional, but it performs unnecessary comparisons in later iterations. After each pass of the outer loop (controlled by i), the largest unsorted element 'bubbles up' to its final position at the end of the array. You can optimize this by reducing the upper bound of this inner loop with each outer loop pass. Consider adjusting the loop's condition to j < arr.length - 1 - i to avoid comparing elements that are already in their correct sorted position.
