'+' or parseInt() - which one is efficient to convert string to integer in javascript
<p>In JavaScript codes, I have seen people using '+' character to convert string to integer as in - </p>

<pre><code>var i = +"2";
</code></pre>

<p>another way is just using parseInt() method as following - </p>

<pre><code>var i = parseInt("2");
</code></pre>

<p>I want to know which one is efficient? </p>

<p>Sorry I should also add that, I am dealing with integers only and the data is huge so even a little difference in performance would be good for me.</p>
