Question

What happens if we give Array.splice() a howMany parameter of 0?

Answer 1

The Array.splice() method with a howMany parameter of 0 does not remove any elements, but it can add new elements at a specific index.

Step-by-step explanation:

When we use the Array.splice() method in JavaScript with a howMany parameter of 0, no elements are removed from the array. Instead, this method can be used to add new elements to an array at a specific index. If additional parameters are provided after howMany, representing the items to be added, those items will be inserted into the array at the specified index without any element being removed.
