Slice to collect elements of an array

<script type="text/javascript">
var names=new Array();
names[0] = "John";
names[1] = "Mike";
names[2] = "Rose";
names[3] = "Steve";
names[4] = "Rabin";

document.write(names.slice(3));  //Steve,Rabin
By using slice method we can collect a part of the array. Using slice we can specify were to start and by using another optional argument we can pass to tell where to end.
array.slice(start, [end]);
The original array remians same after using slice() method.

If we don't specify the start value then splice will start returning from 0 element or first element.

The second argument end is optional and if we don't specify then all elements staring from start till the end of the array will be returned.

Example 2

Last element position is -1,
document.write(names.slice(-3,-1)); // Rose,Steve
document.write(names.slice(-5,2)); // John,Mike
