How to use the slice() method?
The slice() method can create a new array based on the current array, and will not have any impact on the original array.
Function: Return the selected element from the existing array.
Syntax: arrayObject.slice(start,end)
##Parameters: start Required. Specifies where to start the selection. If negative, it specifies the position from the end of the array. That is, -1 refers to the last element, -2 refers to the second to last element, and so on. end Optional. Specifies where the selection ends. This parameter is the array index at the end of the array fragment. If this parameter is not specified, the split array contains all elements from start to the end of the array. If this parameter is negative, it specifies the elements starting from the end of the array.
Return: Returns a new array containing the elements in arrayObject from start to end (excluding this element).
Note: Please note that this method does not modify the array, but returns a subarray. If you want to delete a segment of elements from an array, you should use the method Array.splice().
Note: You can use negative values to select elements from the tail of the array. If end is not specified, the slice() method selects all elements from start to the end of the array.
