Why the ampersands in this jQueryfunction
<p>I'm looking at some code for a shoutbox at <a href="http://yensdesign.com/2009/01/create-a-shoutbox-using-php-and-ajax-jquery/" rel="nofollow">yensdesigns</a>, and in this function it's checking to make sure the form fields are complete. What's with all the ampersands? Is that important? I'm a newbie/hobbyist, don't really get what he's doing with that?</p>

<pre><code>//check if all fields are filled  
function checkForm(){  
    if(inputUser.attr("value") &amp;amp;amp;amp;amp;amp;amp;&amp;amp;amp;amp;amp;amp;amp; inputMessage.attr("value"))  
        return true;  
    else  
        return false;  
}  
</code></pre>

<p>Is it the same if I write</p>

<pre><code>  //check if all fields are filled  
    function checkForm(){  
        if(inputUser.attr("value"); inputMessage.attr("value"))  
            return true;  
        else  
            return false;  
    }  
</code></pre>
