remove values from a string
<p>Does anyone know how I would remove all leading zeros from a string.</p>

<pre><code>var str = 000890
</code></pre>

<p>The string value changes all the time so I need it to be able to remove all 0s before a number greater than 0. So in the example above it needs to remove the first three 0s. So the result would be 890</p>
