+ * Like [`each`]{@link module:Collections.each}, except that it passes the key (or index) as the second argument
+ * to the iteratee.
+ *
+ * @name eachOf
+ * @static
+ * @memberOf module:Collections
+ * @method
+ * @alias forEachOf
+ * @category Collection
+ * @see [async.each]{@link module:Collections.each}
+ * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
+ * @param {AsyncFunction} iteratee - A function to apply to each
+ * item in `coll`.
+ * The `key` is the item's key, or index in the case of an array.
+ * Invoked with (item, key, callback).
+ * @param {Function} [callback] - A callback which is called when all
+ * `iteratee` functions have finished, or an error occurs. Invoked with (err).
+ * @returns {Promise} a promise, if a callback is omitted
+ * @example
+ *
+ * // dev.json is a file containing a valid json object config for dev environment
+ * // dev.json is a file containing a valid json object config for test environment
+ * // prod.json is a file containing a valid json object config for prod environment
