let arr = [10, 20, 30, 40, 50]; console.log(arr[-1]); // Output: 50 console.log(arr[-2]); // Output: 40
Note that negative indices are relative to the end of the array, so
arr[-1] returns the last element in the array (50),
arr[-2] returns the second to last element (40), and so on.
Keep in mind that when using a negative index to access elements in an array, if the absolute value of the index is greater than the length of the array, it will return
