/**
26
 * Returns the first value in `coll` that passes an async truth test. The
27
 * `iteratee` is applied in parallel, meaning the first iteratee to return
28
 * `true` will fire the detect `callback` with that result. That means the
29
 * result might not be the first item in the original `coll` (in terms of order)
30
 * that passes the test.
31

    
32
 * If order within the original `coll` is important, then look at
33
 * [`detectSeries`]{@link module:Collections.detectSeries}.

 * @param {Array|Iterable|Object} coll - A collection to iterate over.
42
 * @param {AsyncFunction} iteratee - A truth test to apply to each item in `coll`.
43
 * The iteratee must complete with a boolean value as its result.
44
 * Invoked with (item, callback).
45
 * @param {Function} [callback] - A callback which is called as soon as any
46
 * iteratee returns `true`, or after all the `iteratee` functions have finished.
47
 * Result will be the first item in the array that passes the truth test
48
 * (iteratee) or the value `undefined` if none passed. Invoked with
49
 * (err, result).
50
 * @example
51
 *
52
 * async.detect(['file1','file2','file3'], function(filePath, callback) {
53
 *     fs.access(filePath, function(err) {
54
 *         callback(null, !err)
55
 *     });
56
 * }, function(err, result) {
57
 *     // result now equals the first file in the list that exists
