What is the function of an Array object that adds and/or removes elements from an array?

The function of an Array object that adds and/or removes elements from an array is called splice() in JavaScript.

Here's how it works:

1. Adding Elements:

   • Syntax: array.splice(index, 0, item1, ....., itemX)
   • This will add item1, item2, ..., itemX to the array at the specified index position. The 0 indicates that no elements should be deleted.

2. Removing Elements:

   • Syntax: array.splice(index, n)
   • This will remove 'n' elements from the array starting at the specified index.

3. Replacing Elements:

   • Syntax: array.splice(index, n, item1, ....., itemX)
   • This will remove 'n' elements from the array starting at the specified index and replaces them with item1, item2, ..., itemX.

In all cases, the splice() function modifies the original array and returns an array with the deleted items (if any).
