Note that the array_unshift() implementation given here prepends the array arguments in the wrong order.

As an example:
<pre><code>
var names=['van', 'Zonneveld'];
array_unshift(names,'Kevin','Tim')
// returns 4
//names is now ['Tim','Kevin','van', 'Zonneveld']
</code></pre>

The function should be altered to:
<pre><code>
function array_unshift(/* assumes at least 1 argument passed - the array */){
var i=arguments.length;
     while(--i!==0){
     arguments[0].unshift(arguments[i]);
    }
return arguments[0].length;
}
</code></pre>

As an example:
<pre><code>
var names=['van', 'Zonneveld'];
array_unshift(names,'Kevin','Tim')
// returns 4
//names is now ['Kevin','Tim','van', 'Zonneveld']
</code></pre>
