What is the significance of this js code in apple “The 50 Billion Apps Countdown Promotion”?
<p>this is the promotion page:
<a href="http://www.apple.com/itunes/50-billion-app-countdown/" rel="nofollow">http://www.apple.com/itunes/50-billion-app-countdown/</a></p>

<p>and it link a js:
<a href="http://www.apple.com.cn/v/itunes/50-billion-app-countdown/a/scripts/counter.js" rel="nofollow">http://www.apple.com.cn/v/itunes/50-billion-app-countdown/a/scripts/counter.js</a></p>

<pre><code>    AC.onDOMReady(function() {
var e = "j", t = new Counter({
    container: AC.Element.selectAll(".counter")[0],
    dataURL: "/itunes/store/counters/il6ark7ec." + e + "s",
    staticImagePath: "http://images.apple.com/itunes/shared/counter/images/counter_noscript.png",
    targetCount: 50000000000,
    stopAtTargetCount: true
});
</code></pre>

<p>});</p>

<p>so Splice the string </p>

<p><code>var e="j"</code></p>

<p><code>"/itunes/store/counters/il6ark7ec." + e + "s"</code> </p>

<p>to</p>

<p><code>http://www.apple.com.cn/itunes/store/counters/il6ark7ec.js</code></p>

<p>is it useful? or just only for fun..?</p>
