docs: The opposite of `_.filter`; this method returns the elements of `collection`
  that `predicate` does **not** return truthy for.

  { 'user': 'fred',   'age': 40, 'active': true }

  // => objects for ['fred']
  
  // The `_.matches` iteratee shorthand.
  _.reject(users, { 'age': 40, 'active': true });
  // => objects for ['barney']
  
  // The `_.matchesProperty` iteratee shorthand.
  _.reject(users, ['active', false]);
  // => objects for ['fred']
  
  // The `_.property` iteratee shorthand.
  _.reject(users, 'active');
  // => objects for ['barney']
