Id for setInterval. How does it work?
<p>Suppose I have an array that stores all my ids used for <code>setInterval</code>.</p>

<p>What if I want to create an id, dynamically... can I do like this?</p>

<pre><code>id_array.push(++id_var) = setInterval(function, milliseconds);
</code></pre>

<p>See?</p>

<p>I also have a variable, called 'id_var', that I believe, if I increment it, it will give me, a new 'id'.</p>

<p>Is this code correct?</p>
