for(i=0;i<names.length;i++)
{
document.write(names[i]+ "<br>");
}
</script>

From the output we see that last element is Four.
We want to remove Four.
Lets see the following example:

Example: 2

<script type="text/javascript">
var names=new Array("One" , "Two", "Three", "Four");
for(i=0;i<names.length;i++)
{
document.write(names[i]+ "<br>");
}
names.pop(); //Now our names array contains three elements.
document.write("Now we will not see last element <br><br>");
for(i=0;i<names.length;i++)
{
document.write(names[i]+ "<br>");
}
</script>

Output

The pop() method also returns the element which is poped or removed.

<script type="text/javascript">
var names=new Array("One" , "Two", "Three", "Four");
document.write(names.pop() + "<br>");
</script>
