 * The same as [`filter`]{@link module:Collections.filter} but runs a maximum of `limit` async operations at a
 * time.

 * @method
 * @see [async.filter]{@link module:Collections.filter}
 * @alias selectLimit
 * @category Collection
 * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
 * @param {number} limit - The maximum number of async operations at a time.
 * @param {Function} iteratee - A truth test to apply to each item in `coll`.
 * The `iteratee` is passed a `callback(err, truthValue)`, which must be called
 * with a boolean argument once it has completed. Invoked with (item, callback).
 * @param {Function} [callback] - A callback which is called after all the
 * `iteratee` functions have finished. Invoked with (err, results).
 * @returns {Promise} a promise, if no callback provided
