Final answer:
If the index given to Array.splice() is greater than the length of the array, the method removes elements from the given index to the end of the array.
Step-by-step explanation:
If you give Array.splice() an index greater than the length of the array, the method will remove elements from the given index to the end of the array.
For example, let's say you have an array with the values [1, 2, 3, 4, 5] and you call Array.splice(7). Since the array only has 5 elements, this call will remove all elements from index 7 to the end of the array, resulting in an empty array. The original array would be modified to [].
In summary, when the index provided to Array.splice() is greater than the length of the array, the method simply removes elements from the given index to the end of the array.
When you use Array.splice() in JavaScript and provide an index that is greater than the length of the array, the method will not remove any elements, as there are none beyond that index. However, if items are to be added using the splice method, they will be added to the end of the array. Thus, the splice function will still execute the addition operation. The original array will then contain the new elements at the end, but no elements will be removed because the start index did not reference an existing position within the array.
