What does '/=' operator mean in JavaScript?
<p>I came across this looking at the source for some physics animations in JavaScript found <a href="https://github.com/iamralpht/iamralpht.github.io/blob/master/physics/androidwear.js#L107" rel="nofollow">here on github</a> where he's written this</p>

<pre><code>if (this._position &lt; 0) this._position /= 3;
</code></pre>

<p>A quick Google yielded nothing, anyone know?</p>
