The Array object is used to store multiple values in a single variable.

JavaScript Array Object

The following code creates an Array object called myCars:

There are two ways of adding values to an array (you can add as many values as you need to define as many variables you require).

var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

Now your array contains:

var myCars=new Array("Saab","Volvo","BMW");

Access an Array

You can refer to a particular element in an array by referring to the name of the array and the index number. The index number starts at 0.

The following code line:

document.write(myCars[0]);

will result in the following output:

Saab

Modify Values in an Array

To modify a value in an existing array, just add a new value to the array with a specified index number:

myCars[0]="Opel";

Now, the following code line:

document.write(myCars[0]);

will result:
Opel
