This is another way to display all elements and if we give line break <br> as delimiter then all elements we can display vertically in any web page. We need not loop through by using length property.

We can directly display elements by using document.write or we can assign it to one string variable and then display.
var str=scripts.join(" : ");
document.write(str);
Here is the complete code for displaying elements of an array using join
<script type="text/javascript">
var scripts = new Array();
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";
var str=scripts.join(" : ");
document.write(str);
//document.write(scripts.join(" <br> "));
</script>
The output of the above code is here
PHP : ASP : JavaScript : HTML 
You can use line break <br> to generate a list by using the last line of the above code.
