/** |
|
* This method is like `_.mean` except that it accepts `iteratee` which is |
|
* invoked for each element in `array` to generate the value to be averaged. |
|
* 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 {number} Returns the mean. |
|
* @example |
|
* |
|
* var objects = [{ 'n': 4 }, { 'n': 2 }, { 'n': 8 }, { 'n': 6 }]; |
|
* |
|
* _.meanBy(objects, function(o) { return o.n; }); |
|
* // => 5 |
|
* |
|
* // The `_.property` iteratee shorthand. |
|
* _.meanBy(objects, 'n'); |
|
* // => 5 |
