Is bad/good/optionnal to defined vars after created them?
<p>Reading the code of many javascript libraries, I see that many developers use to set variables as soon as they were created them.</p>

<pre><code>var i = 0,
var c = 0;
</code></pre>

<p>I prefer instead to defined vars after created them.</p>

<pre><code>var i,
    c;

i = 0;
c = 0;
</code></pre>

<p>But there might be an explanation about why this or that way?</p>
