22   * Returns the first value in `coll` that passes an async truth test. The
23   * `iteratee` is applied in parallel, meaning the first iteratee to return
24   * `true` will fire the detect `callback` with that result. That means the
25   * result might not be the first item in the original `coll` (in terms of order)
26   * that passes the test.
27  
28   * If order within the original `coll` is important, then look at
29   * [`detectSeries`]{@link module:Collections.detectSeries}.

37   * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
38   * @param {AsyncFunction} iteratee - A truth test to apply to each item in `coll`.
39   * The iteratee must complete with a boolean value as its result.
40   * Invoked with (item, callback).
41   * @param {Function} [callback] - A callback which is called as soon as any
42   * iteratee returns `true`, or after all the `iteratee` functions have finished.
43   * Result will be the first item in the array that passes the truth test
44   * (iteratee) or the value `undefined` if none passed. Invoked with
45   * (err, result).
46   * @returns A Promise, if no callback is passed
47   * @example
48   *
49   * async.detect(['file1','file2','file3'], function(filePath, callback) {
