How to prevent jquery dot evaluation when there are no matching elements

$('#someElement').somePlugin(someArgs);

The above jquery statement produces the following error:

Uncaught TypeError: Object [object Object] has no method 'somePlugin'

I know that somePlugin does not exist in this context, but it shouldn't matter because #someElement also does not exist.

What's the best way to prevent the right side of the dot from evaluating when there are no matching elements?

There are many ways, one is: 

var element = $('#someElement');
element.somePlugin && element.somePlugin(someArgs);

You could also test if the plugin itself is loaded: 

if ( $.fn.somePlugin ) { 
  // stuff...
}
