how to simplify my conditional statement?
<p>I am trying to simplify the following codes. The codes seem to redundant to me. Are there anyone here can help me out? Thanks a lot!</p>

<pre><code>if(area.regionCode=='0' || area.regionCode==null){  

    var fakecode=area.region.substring(0, area.region.length - 1);
        area.region= fakecode +i;
}
</code></pre>
