DRYing out some code
<p>I'm drying to DRY up this code from the jQuery source:</p>

<pre><code>cssNumber: {
    "fillOpacity": true,
    "fontWeight": true,
    "lineHeight": true,
    "opacity": true,
    "orphans": true,
    "widows": true,
    "zIndex": true,
    "zoom": true
}
</code></pre>

<p>I suggest the following. Can it be done better?</p>

<pre><code>cssNumber: {}
"fillOpacity fontWeight lineHeight opacity orphans windows zIndex zoom"
    .split(" ")
    .forEach(function() {
        cssNumber.name = true;
    });
</code></pre>
