/** |
|
* 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). |

* @category Math |
|
* @param {Array} array The array to iterate over. |
|
* @param {Function} [iteratee=_.identity] The iteratee invoked per element. |
|
* @returns {*} Returns the minimum value. |
|
* @example |
|
* |
|
* var objects = [{ 'n': 1 }, { 'n': 2 }]; |
|
* |
|
* _.minBy(objects, function(o) { return o.n; }); |
|
* // => { 'n': 1 } |
|
* |
|
* // The `_.property` iteratee shorthand. |
|
* _.minBy(objects, 'n'); |
|
* // => { 'n': 1 } |
