Remarks
Use the insert function to insert an item into a specified index of an Array object. The index value of items that are greater than index is increased by one.
Calling the insert function and passing a negative value for index counts backward from the end of the array. Floating point values are rounded down to a whole number value.
Example
The following example shows how to use the insert function to insert an item into an array.
var a = ['a', 'b', 'd', 'e'];
Array.insert(a, 2, 'c');

alert(a);
