How do I match the numbers sequence rising?
<p>I have a string contains just numbers. Something like this:</p>

<pre><code>var numb = "5136789431235";
</code></pre>

<p>And I'm trying to match ascending numbers which are two or more digits. In string above I want this output:</p>

<pre><code>var numb = "5136789431235";
//             ^^^^  ^^^
</code></pre>

<p>Actually I can match a number which has two or more digits: <code>/[0-9]{2,}/g</code>, But I don't know how can I detect being ascending? </p>
