Hello Friend,

Try this:

<script type="text/javascript">
var lang = new Array();
lang[0] = "C";
lang[1] = "Java";
lang[2] = ".NET";
lang[3] = "PERL";
document.write(lang.join("<br>"));
document.write("<br><b>Adding element 'Python' from the Front</b><br>");
lang.unshift("Python");
document.write(lang.join("<br>"));
document.write("<br><b>Adding element 'Basic' from the Back</b><br>");
lang.push("Basic");
document.write(lang.join("<br>"));
document.write("<br><b>Removing element from the Front</b><br>");
lang.shift();
document.write(lang.join("<br>"));
document.write("<br><b>Removing element from the Back</b><br>");
