- * @param {Array|Iterable|Object} fns - A collection of asynchronous functions to all
- * call with the same arguments
+ * @param {Array|Iterable|Object} fns - A collection of asynchronous functions
+ * to all call with the same arguments
* @param {...*} [args] - any number of separate arguments to pass to the
* function.
* @param {Function} [callback] - the final argument should be the callback,
* called when all functions have completed processing.
- * @returns {Function} - If only the first argument is provided, it will return
- * a function which lets you pass in the arguments as if it were a single
- * function call.
+ * @returns {Function} - If only the first argument, `fns`, is provided, it will
+ * return a function which lets you pass in the arguments as if it were a single
+ * function call. The signature is `(..args, callback)`. If invoked with any
+ * arguments, `callback` is required.
* @example
*
* async.applyEach([enableSearch, updateSchema], 'bucket', callback);
