Splice Slice Difference _ basic knowledge

1, slice method (Array)
Returns a section of an array.

Arrayobj.slice (start, [end])

Parameters
Arrayobj

Required option. An Array object.

Start

Required option. The starting element of the part specified in Arrayobj is the zero-based subscript.

End

Options available. The end element of the part specified in Arrayobj is the zero-based subscript.

Description
The slice method returns an Array object that contains the specified portion of the arrayobj.

The slice method is copied to the element specified by end, but does not include the element. If start is negative, it is the length + start processing, where length is the size of the array. If end is negative, it is treated as length + end where length is the length of the array. If End is omitted, the slice method is copied to the ending of arrayobj. If End appears before start, no elements are copied into the new array.

Example
In the following example, all elements in the myarray are copied to the NewArray except for the last element:

NewArray = Myarray.slice (0,-1)
2, Splice method
Removes one or more elements from an array and, if necessary, inserts a new element at the position of the removed element, returning the removed element.

Arrayobj.splice (Start, DeleteCount, [item1[, item2[, ...) [, Itemn]]]

Parameters
Arrayobj

Required option. An Array object.

Start

Required option. Specifies that the starting position of the element is removed from the array, which is calculated starting at 0.

DeleteCount

Required option. The number of elements to remove.

Item1, item2,.. ., itemn

Required option. The new element to insert at the location of the removed element.

Description
The splice method modifies arrayobj by removing the specified number of elements starting from the start position and inserting new elements. The return value is a new Array object that consists of the removed element.
