Regexp plurals - how?
<p>I want to detect two versions of the same thing, plural and now</p>

<p>eg:</p>

<p>"piece" and "pieces" should both return a match.</p>

<pre><code>var re_1 = new RegExp("how many piece", "i");
</code></pre>

<p>or </p>

<pre><code>var re_1 = new RegExp("how many pieces", "i");
</code></pre>

<p>How do I form a RegExp expression in Javascript to detect both singular and plural in the same pattern?</p>
