<pre><code>var numbers = new Array('1','2','4','5','6','7','8','9','10');
</code></pre>

<p>I have a JavaScript Array and now want to randomly choose four different numbers from it and then express it on the page (through <code>document.write</code>). Obviously each time the page is reloaded by the user it would show four different random numbers.</p>
