| 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
