unshift Method
Inserts specified elements into the beginning of an array.
function unshift([item1 : Object [, ... [, itemN : Object]]]) : Array
- item1, ... , itemN
Optional. Elements to insert at the start of the Array.
The unshift method inserts elements into the start of an array, so they appear in the same order in which they appear in the argument list.
The following example illustrates the use of the unshift method.
var ar = new Array();
ar.unshift(10, 11);
ar.unshift(12, 13, 14);
var s = ar.toString();
print (s);
// Output: 12,13,14,10,11
