- * This method is like `_.max` except that it accepts `iteratee` which is
- * invoked for each element in `array` to generate the criterion by which
- * the value is ranked. The iteratee is invoked with one argument: (value).
- *
- * @static
- * @memberOf _
- * @since 4.0.0
- * @category Math
- * @param {Array} array The array to iterate over.
- * @param {Function} [iteratee=_.identity] The iteratee invoked per element.
- * @returns {*} Returns the maximum value.
- * @example
- *
- * var objects = [{ 'n': 1 }, { 'n': 2 }];
- *
- * _.maxBy(objects, function(o) { return o.n; });
- * // => { 'n': 2 }
- *
- * // The `_.property` iteratee shorthand.
- * _.maxBy(objects, 'n');
- * // => { 'n': 2 }
