+/**
+ * Reduces `collection` to a value which is the accumulated result of running
+ * each element in `collection` through `iteratee`, where each successive
+ * invocation is supplied the return value of the previous. If `accumulator`
+ * is not provided the first element of `collection` is used as the initial
+ * value. The `iteratee` is bound to `thisArg` and invoked with four arguments:
+ * (accumulator, value, index|key, collection).
+ *
+ * Many lodash methods are guarded to work as iteratees for methods like
+ * `_.reduce`, `_.reduceRight`, and `_.transform`.
+ *
+ * The guarded methods are:
+ * `assign`, `defaults`, `defaultsDeep`, `includes`, `merge`, `sortByAll`,
+ * and `sortByOrder`

+ * @category Collection
+ * @param {Array|Object|string} collection The collection to iterate over.
+ * @param {Function} [iteratee=_.identity] The function invoked per iteration.
+ * @param {*} [accumulator] The initial value.
+ * @param {*} [thisArg] The `this` binding of `iteratee`.
+ * @returns {*} Returns the accumulated value.
+ * @example
+ *
+ * _.reduce([1, 2], function(total, n) {
+ *   return total + n;
+ * });
+ * // => 3
+ *
+ * _.reduce({ 'a': 1, 'b': 2 }, function(result, n, key) {
+ *   result[key] = n * 3;
+ *   return result;
+ * }, {});
+ * // => { 'a': 3, 'b': 6 } (iteration order is not guaranteed)
