Should a variable commonly evaluated as true in the "if" or the "else"?
<p>If I have a variable from a dataset that evaluates as true most of the time should I put it in the "if" clause or the "else" clause. Is one faster that the other? I am sure it depends on things like the JavaScript engine and/or the operating system as it is coverted to Machine language.</p>

<p>Like this:</p>

<pre><code>var usualyTrue;
// some more code here...
if(usualTrue)
    //do something
else
    //do something else
</code></pre>

<p>or like this:</p>

<pre><code>var usualyTrue;
// some more code here...
if(!usualTrue)
    //do something
else
    //do something else
</code></pre>
