 * This method is like `min` 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 5.8.0
 * @category Math
 * @param array The array to iterate over.
 * @param iteratee The iteratee invoked per element.
 * @returns Returns the minimum value.
 * @example
 *
 * ```js
 * const objects = [{ 'n': 1 }, { 'n': 2 }]
 *
 * minBy(objects, ({ n }) => n)
 * // => { 'n': 1 }
 * ```
