6 * This method is like `_.min` except that it accepts `iteratee` which is
7 * invoked for each element in `array` to generate the criterion by which
8 * the value is ranked. The iteratee is invoked with one argument: (value).
9 *
10 * @static
11 * @memberOf _
12 * @since 4.0.0
13 * @category Math
14 * @param {Array} array The array to iterate over.
15 * @param {Function} [iteratee=_.identity] The iteratee invoked per element.
16 * @returns {*} Returns the minimum value.
17 * @example
18 *
19 * var objects = [{ 'n': 1 }, { 'n': 2 }];
20 *
21 * _.minBy(objects, function(o) { return o.n; });
22 * // => { 'n': 1 }
23 *
24 * // The `_.property` iteratee shorthand.
25 * _.minBy(objects, 'n');
26 * // => { 'n': 1 }
