Javascript Incompatibilities/Inconsistencies
<p>I'm looking to do a presentation in a couple of weeks and was wondering: What are the top ten Javascript incompatibilities that you look out for when developing? What trips you up? I can start with one:</p>

<pre><code>var somevar = {
 'internet': 'explorer',
 'hates': 'trailing',
 'commas': 'in',
 'json': 'code', // oh noes!
}
</code></pre>

<p>What are some other common gotchas that can't or aren't fixed by using a framework like jQuery or base? </p>
