The Array object lets you store multiple values in a single
variable. An array is used to store a collection of data, but it is
often more useful to think of an array as a collection of variables of
the same type.
The Array parameter is a list of strings or integers. When you specify a single numeric parameter with the Array constructor, you specify the initial length of the array.
You can retrive array using indexs like arr[0], arr[1].
Splice Method:
Javascript array slice() method extracts a section of an array and returns a new array. It returns the extracted array based on the passed parameters.
Array.splice(startIndex,ItemToRemove,items);
It will add or remove to or from array as per requirement.
var fruits = ["Chair", "Table", "Mat"];
fruits.splice(2,0,"Glass","Bottle");
Output will be:["Chair", "Table", "Glass","Bottle","Mat"]
Unshift method:
Javascript array unshift() method adds one or more elements to the beginning of an array and returns the new length of the array.

Hope it helps you. I will come up with more ideas in future.
var arr = new Array( "Jon", "XXX", "Kit" );

syntex:
array.unshift( element1, ..., elementN );
You can find below example to get it more clearly:
<html> <head> <title>JavaScript Array unshift Method</title> </head> <body> <script type="text/javascript"> var arr = new Array("orange", "mango", "banana", "sugar"); var length = arr.unshift("water"); document.write("Returned array is : " + arr ); document.write("<br /> Length of the array is : " + length ); </script> </body> </html>
Hope it helps you. I will come up with more ideas in future.
