- /**
- * Run the `tasks` collection of functions in parallel, without waiting until
- * the previous function has completed. If any of the functions pass an error to
- * its callback, the main `callback` is immediately called with the value of the
- * error. Once the `tasks` have completed, the results are passed to the final
- * `callback` as an array.
- *
- * **Note:** `parallel` is about kicking-off I/O tasks in parallel, not about
- * parallel execution of code. If your tasks do not use any timers or perform
- * any I/O, they will actually be executed in series. Any synchronous setup
- * sections for each task will happen one after the other. JavaScript remains
- * single-threaded.
- *
- * **Hint:** Use [`reflect`]{@link module:Utils.reflect} to continue the
- * execution of other tasks when a task fails.
- *
- * It is also possible to use an object instead of an array. Each property will
- * be run as a function and the results will be passed to the final `callback`
- * as an object instead of an array. This can be a more readable way of handling
- * results from {@link async.parallel}.
- *

- * @memberOf module:ControlFlow

- * @param {Array|Iterable|Object} tasks - A collection of
- * [async functions]{@link AsyncFunction} to run.
- * Each async function can complete with any number of optional `result` values.
- * @param {Function} [callback] - An optional callback to run once all the
- * functions have completed successfully. This function gets a results array
- * (or object) containing all the result arguments passed to the task callbacks.
- * Invoked with (err, results).
- *
- * @example
- * async.parallel([
- * function(callback) {
- * setTimeout(function() {
- * callback(null, 'one');
- * }, 200);
- * },
- * function(callback) {
- * setTimeout(function() {
- * callback(null, 'two');
- * }, 100);
- * }
- * ],
- * // optional callback
- * function(err, results) {
- * // the results array will equal ['one','two'] even though
- * // the second function had a shorter timeout.
- * });
- *
- * // an example using an object instead of an array
- * async.parallel({
- * one: function(callback) {
- * setTimeout(function() {
- * callback(null, 1);
- * }, 200);
- * },
- * two: function(callback) {
- * setTimeout(function() {
- * callback(null, 2);
- * }, 100);
- * }
- * }, function(err, results) {
- * // results is now equals to: {one: 1, two: 2}
