 * - property (String): The name of the property to fetch.

 * Pre-baked implementation for a common use-case of [[Enumerable#collect]]
 * and [[Enumerable#each]]: fetching the same property for all of the
 * elements. Returns an array of the property values.
 *
 * <h5>Example</h5>
 *
 * ['hello', 'world', 'this', 'is', 'nice'].pluck('length');
 * // -> [5, 5, 4, 2, 4]
