<p>What is the difference between this two ways of initializing variables?</p>

<pre><code>var $val = 'something'

     OR

var val = 'something'
</code></pre>

<p>as I see they are the same thing.</p>

<p>Maybe in this case <code>$</code> is only the part of name in variable?
(it will become a meaningless question in that case:/)</p>

<p>Thanks</p>
