- * This method is like `_.reduce` except that it iterates over elements of

- *
- * @static
- * @memberOf _
- * @since 0.1.0
- * @category Collection
- * @param {Array|Object} collection The collection to iterate over.
- * @param {Function} [iteratee=_.identity] The function invoked per iteration.
- * @param {*} [accumulator] The initial value.
- * @returns {*} Returns the accumulated value.
- * @see _.reduce
- * @example
- *
- * var array = [[0, 1], [2, 3], [4, 5]];
- *
- * _.reduceRight(array, function(flattened, other) {
- * return flattened.concat(other);
- * }, []);
- * // => [4, 5, 2, 3, 0, 1]
