-/**
- * Reduces `coll` into a single value using an async `iteratee` to return each
- * successive step. `memo` is the initial state of the reduction. This function
- * only operates in series.
- *
- * For performance reasons, it may make sense to split a call to this function
- * into a parallel map, and then use the normal `Array.prototype.reduce` on the
- * results. This function is for situations where each step in the reduction
- * needs to be async; if you can get the data before reducing it, then it's
- * probably a good idea to do so.
- *
- * @name reduce
- * @static
- * @memberOf module:Collections
- * @method
- * @alias inject
- * @alias foldl
- * @category Collection
- * @param {Array|Iterable|Object} coll - A collection to iterate over.
- * @param {*} memo - The initial state of the reduction.
- * @param {Function} iteratee - A function applied to each item in the
- * array to produce the next step in the reduction. The `iteratee` is passed a
- * `callback(err, reduction)` which accepts an optional error as its first
- * argument, and the state of the reduction as the second. If an error is
- * passed to the callback, the reduction is stopped and the main `callback` is
- * immediately called with the error. Invoked with (memo, item, callback).
- * @param {Function} [callback] - A callback which is called after all the
- * `iteratee` functions have finished. Result is the reduced value. Invoked with
- * (err, result).
- * @example
- *
- * async.reduce([1,2,3], 0, function(memo, item, callback) {
- * // pointless async:
- * process.nextTick(function() {
- * callback(null, memo + item)
- * });
- * }, function(err, result) {
- * // result is now equal to the last value of memo, which is 6
- * });
