/**
|
||
|
|
* 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).

|
||
|
|
* @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 }];

* // The `_.property` iteratee shorthand.

|
* _.meanBy(objects, 'n');
