<p>the first</p>

<pre><code>(function() {
    var slice = Array.prototype.slice,
        aArguments = slice.apply(arguments);
})(10, 20, 30);
</code></pre>

<p>the second</p>

<pre><code>(function() {
    var aArguments = [].slice.apply(arguments);
})(10, 20, 30);
</code></pre>

<p>what's the difference?</p>

<p>only ​​Speed？</p>
