pluck

pluck(property) ⇒ array

Get values from a named property of each element in the collection, with null and undefined values filtered out.

$('body > *').pluck('nodeName') // => ["DIV", "SCRIPT"]

// implementation of Zepto's `next` method
$.fn.next = function(){ 
  return $(this.pluck('nextElementSibling')) 
}

This is a Zepto-provided method that is not part of the jQuery API.
