  /**
   * Creates an array of elements split into two groups, the first of which
   * contains elements `predicate` returns truthy for, the second of which
   * contains elements `predicate` returns falsey for. The predicate is
   * invoked with one argument: (value).
   *
   * @static
   * @memberOf _
   * @since 3.0.0
   * @category Collection
   * @param {Array|Object} collection The collection to iterate over.
   * @param {Array|Function|Object|string} [predicate=_.identity]
   *  The function invoked per iteration.
   * @returns {Array} Returns the array of grouped elements.
   * @example
   *
   * var users = [
   *   { 'user': 'barney',  'age': 36, 'active': false },
   *   { 'user': 'fred',    'age': 40, 'active': true },

   * // => objects for [['pebbles'], ['barney', 'fred']]
