n = n +1 is faster than n++ or ++n, why?
<p>Check this test case: <a href="http://jsperf.com/n-n-1-or-n">http://jsperf.com/n-n-1-or-n</a></p>

<pre><code>n = n + 1;
</code></pre>

<p>is faster than</p>

<pre><code>n++;
</code></pre>

<p>and</p>

<pre><code>++n;
</code></pre>

<p>Any clue about why the first writing is so much faster on many browsers ?</p>
