Question

What happens if we give Array.splice() a howMany parameter greater than the number of elements left in the array starting at index?

Answer 1

If howMany parameter in Array.splice() is greater than elements left in array, it removes all remaining elements.

Step-by-step explanation:

The Array.splice() method in JavaScript is used to modify an array by removing, replacing, or adding elements. If the howMany parameter passed to Array.splice() is greater than the number of elements left in the array starting at the specified index, it will remove all the remaining elements from the array.

For example, consider an array arr with 5 elements. If we call arr.splice(2, 4) (starting from index 2 and howMany is 4), it will remove the last 3 elements as there are only 3 elements left starting from index 2.
