      5  * @private
      6  * @param {Array|Object} collection The collection to iterate over.
      7  * @param {Function} iteratee The function invoked per iteration.
      8  * @param {*} accumulator The initial value.
      9  * @param {boolean} initAccum Specify using the first or last element of
     10  *  `collection` as the initial value.
     11  * @param {Function} eachFunc The function to iterate over `collection`.
     12  * @returns {*} Returns the accumulated value.
