Removing all elements of an array in JavaScript

Removing all elements by making length zero.

 <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>

By re-declaring the array to new variable.

scripts = [];

var scripts = new Array();
