JavaScript supports a more complicated data type known as an array. An array is a collection of individual values grouped together. An array essentially contains a series of numbered containers into which you can place values. Each container can contain a string, a number, or any other data type.
To create a new array, you create a new instance of the Array object:
var arrayName = new Array(number of elements);
The number of elements is just the initial number of elements in the array; you can add more on the fly as you work with the array, but it is a good idea to initialize the array with the likely number of elements you will use.
1. Open a new HTML document in your preferred HTML or text editor.
2. Create the head of the document with opening and closing head
tags:
<head>
</head>
3. Insert a script block in the head of the document:
<head>
<script language="JavaScript">
<!--
// -->
</script>
</head>
4. Create a variable named myArray and initialize it as a new array with five elements:
<body>
<script language="JavaScript">
<!--
var myArray = new Array(5);
// -->
</script>
</body>
5. Save the file and close it.
