| * 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). | |
| * | |
| * @since 4.0.0 | |
| * @category Math | |
| * @param {Array} array The array to iterate over. | |
| * @param {Function} iteratee The iteratee invoked per element. | |
| * @returns {*} Returns the maximum value. | |
| * @example | |
| * | |
| * const objects = [{ 'n': 1 }, { 'n': 2 }] | |
| * | |
| * maxBy(objects, ({ n }) => n) | |
| * // => { 'n': 2 } | |
