/**
 * It runs each task in series but stops whenever any of the functions were

 * passed the result of the successful task. If all tasks fail, the callback
 * will be passed the error and result (if any) of the final attempt.

 * @name tryEach
 * @static
 * @memberOf module:ControlFlow
 * @method
 * @category Control Flow
 * @param {Array|Iterable|AsyncIterable|Object} tasks - A collection containing functions to
 * run, each function is passed a `callback(err, result)` it must call on
 * completion with an error `err` (which can be `null`) and an optional `result`
 * value.
 * @param {Function} [callback] - An optional callback which is called when one
 * of the tasks has succeeded, or all have failed. It receives the `err` and
 * `result` arguments of the last attempt at completing the `task`. Invoked with
 * (err, results).
 * @returns {Promise} a promise, if no callback is passed
 * @example
 * async.tryEach([
 *     function getDataFromFirstWebsite(callback) {
 *         // Try getting the data from the first website
 *         callback(err, data);
 *     },
 *     function getDataFromSecondWebsite(callback) {
 *         // First website failed,
 *         // Try getting the data from the backup website
 *         callback(err, data);
 *     }
 * ],
 * // optional callback
 * function(err, results) {
 *     Now do something with the data.
