* 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). |

| 52 |
* async.detect(['file1','file2','file3'], function(filePath, callback) { |
| 53 |
* fs.access(filePath, function(err) { |
