variables are good and sufficient to hold the single values, But what if we want to store multiple values in a single variable in that case you have to use arrays or objects
Values in arrays are saved index base. Remember that arrays in JavaScript are zero based, arrays are declared using the array literal notation [].
We can categories JavaScript array on base of there style of saving values.
<html>
<script type="text/javascript">
/* Declare array*/
var myself = [];
/* initialize the array */
myself[0] = 'book1';
myself[1] = 'book2';
/*access the value of a specific element*/
alert(myself[1]);
/*OR*/
console.log(myself[1])
</script>
</html>
Arrays can contain various types of data for example
var arrayexample = ["naveen",100,"true","DUCK"];
Multidimensional array, a combination of arrays inside an array, and is considered as more complex type pf array. for example
var example1 = array[100,200,300,400,500];
var example2 = array['hundred', 'two hundred', 'three hundred', 'four hundred', 'five hundred'];
var multidimensionalarray = [example1, example2];
Retrieving value of multidimensional array
alert(multidimensionalarray[1][2]);
we can also declare JavaScript array like below
var myshelf = new Array()
