Removing all elements of an array in JavaScript

 <script type="text/javascript">
var scripts = new Array();
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";
scripts[4] = "SQL";
document.write(scripts.join(","));
document.write("<br>--Now after emptying --<br>");
scripts.length=0; // Emptying all elements
document.write(scripts.join(","));
</script>

PHP,ASP,JavaScript,HTML,SQL
--Now after emptying --

By re-declaring the array to new variable.

scripts = [];

var scripts = new Array();
