     13  * @since 0.1.0
     14  * @category Collection
     15  * @param {Array|Object} collection The collection to iterate over.
     16  * @param {Function} [iteratee=_.identity] The function invoked per iteration.
     17  * @param {*} [accumulator] The initial value.
     18  * @returns {*} Returns the accumulated value.
