Variable length arguments for javascript method

When creating javascrip method, if the parameters passed by caller may be different by any reason, an easy solution is just defining the parameters to empty, then inside the javascript method, accessing the actual parameter from the implicit argument variable.
The arguments variable inside the called function is an array containing the values of all the arguments passed to the function by caller, as shown in the following example:
function test()
{
alert(arguments[1]);
}

test("0","1","2");

Missing closing script tag in html causes javascript runtime error: Object expected

An runtime error: Object expected was returned when testing a simple function in html page's onLoad method. It turns out the error is due to missing closing script tag included
[head]
[script src="testcase.js" /]
[script type="text/javascript"
function callme() {alert("hi");}
[/script]
[/head]
[body onload="callme()"]

After adding the closing tag as shown below, the javascript method callme works properly.

[head]
[script src="testcase.js"] [/script]
[script type="text/javascript"
function callme() {alert("hi");}
[/script]
[/head]
[body onload="callme()"]
