* This method is like `_.sum` except that it accepts `iteratee` which is
|
|
* invoked for each element in `array` to generate the value to be summed.
|
|
* 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 sum.
|
|
* @example
|
|
*
|
|
* var objects = [{ 'n': 4 }, { 'n': 2 }, { 'n': 8 }, { 'n': 6 }];

*
|
|
