Is there a jQuery function to "shortcut" a if/else switch?
<p>Writing if/else statements in the middle of jQuery code doesn't feel right:</p>

<pre><code>if ($("#test").length) {
  // do smth
}
else {
  // do smth else
}
</code></pre>

<p>Is there something similar to:</p>

<pre><code>$("#test").test(function(){
  // do smth
}, 
function(){
  // do smth else
});
</code></pre>
