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

 * @memberOf _
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.

 * var array = [[0, 1], [2, 3], [4, 5]];
