Review Summary
Great work on this task! Your implementation of the sort2 method correctly meets all the requirements. You've successfully added the function to the Array.prototype and it handles both default string-based sorting and custom comparison functions as expected.
I am approving your solution. As a point of feedback for future improvement, you can optimize your bubble sort algorithm. In src/arrayMethodSort.js, consider changing the inner loop's condition to j < this.length - 1 - i. This small change prevents the loop from making redundant comparisons against elements that are already in their final sorted position, improving performance. Keep up the excellent work!

This implementation of bubble sort is functional, but it can be made more efficient. After each pass of the outer loop (i), the largest element for that pass is moved to its correct final position at the end of the unsorted portion. Therefore, the inner loop doesn't need to iterate over the already-sorted elements. You can optimize this by reducing the upper bound of this loop with each outer loop iteration. Consider changing the condition to j < this.length - 1 - i.
