How to delete an entry using JavaScript?

The "delete" operator removes an array element, but oddly does not change the size of the array.
<script type="text/javascript">
var days = ["Sunday","Monday","Tuesday","Wednesday",
"Thursday","Friday","Saturday"];
document.write("Number of days:"+days.length);
delete days[4];
document.write("<br />Number of days:"+days.length);
</script>
This produces
Number of days:7
Number of days:7
