|
|
* SUMMARY: Testing |splice()| method of an Array.
|
|
* Changes the content of an array, adding new elements while removing old elements.
|
|
*
|
|
* Syntax: splice(index, howMany, [element1][, ..., elementN])
|
|
*
|
|
* Parameters: index - index at which to start changing the array.
|
|
* howMany - An integer indicating the number of old array elements to remove.
|
|
* If howMany is 0, no elements are removed. In this case, you should specify at least one new element.
|
|
* element1, ...,elementN - The elements to add to the array. If you don't specify any elements,
|
|
* splice simply removes elements from the array.
