vars on the first parameter of loops
<p>I am aware that I can simplify:</p>

<pre><code>var a;
var b;
</code></pre>

<p>into:</p>

<pre><code>var a, b;
</code></pre>

<p>But can I do the same on loops?</p>

<pre><code>for(var a=0,b=0;a&lt;3;a++){
    //code
}
</code></pre>

<p>Or I need to write <code>var a=0, var b=0</code>?</p>
