/**
 * A relative of `reduce`.  Takes an Object or Array, and iterates over each
 * element in parallel, each step potentially mutating an `accumulator` value.
 * The type of the accumulator defaults to the type of collection passed in.
 *
 * @name transform
 * @static
 * @memberOf module:Collections
 * @method
 * @category Collection
 * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
 * @param {*} [accumulator] - The initial state of the transform.  If omitted,
 * it will default to an empty Object or Array, depending on the type of `coll`
 * @param {AsyncFunction} iteratee - A function applied to each item in the
 * collection that potentially modifies the accumulator.
 * Invoked with (accumulator, item, key, callback).
 * @param {Function} [callback] - A callback which is called after all the
 * `iteratee` functions have finished. Result is the transformed accumulator.
 * Invoked with (err, result).
 * @returns {Promise} a promise, if no callback provided
 * @example
 *
 * // file1.txt is a file that is 1000 bytes in size
 * // file2.txt is a file that is 2000 bytes in size
 * // file3.txt is a file that is 3000 bytes in size
 *
 * // helper function that returns human-readable size format from bytes
 * function formatBytes(bytes, decimals = 2) {
 *   // implementation not included for brevity
 *   return humanReadbleFilesize;
 * }
 *
 * const fileList = ['file1.txt','file2.txt','file3.txt'];
 *
 * // asynchronous function that returns the file size, transformed to human-readable format
 * // e.g. 1024 bytes = 1KB, 1234 bytes = 1.21 KB, 1048576 bytes = 1MB, etc.
 * function transformFileSize(acc, value, key, callback) {
 *     fs.stat(value, function(err, stat) {
 *         if (err) {
 *             return callback(err);
 *         }
 *         acc[key] = formatBytes(stat.size);
 *         callback(null);
 *     });
 * }
 *
 * // Using callbacks
 * async.transform(fileList, transformFileSize, function(err, result) {
 *     if(err) {
 *         console.log(err);
 *     } else {
