The method that Melissa should use is monthName.splice(2, 3, "Mar", "Apr", "May"). This method allows her to insert elements into an array and delete elements from an array simultaneously. In this case, she wants to insert the abbreviations of the spring months into the array, so she would use the splice method to insert "Mar", "Apr", and "May" starting at index 2 of the monthName array, which would replace the element at that index and remove the two following elements.
