 5   * This method is like `_.sortedIndex` except that it accepts `iteratee`
 6   * which is invoked for `value` and each element of `array` to compute their
 7   * sort ranking. The iteratee is invoked with one argument: (value).

10   * @memberOf _

12   * @category Array
13   * @param {Array} array The sorted array to inspect.
14   * @param {*} value The value to evaluate.
15   * @param {Function} [iteratee=_.identity] The iteratee invoked per element.
16   * @returns {number} Returns the index at which `value` should be inserted
17   *  into `array`.
18   * @example
19   *
20   * var objects = [{ 'x': 4 }, { 'x': 5 }];
21   *
22   * _.sortedIndexBy(objects, { 'x': 4 }, function(o) { return o.x; });
