# Promise

Represents an operation that hasn’t completed yet, but is expected in the future.

## Declaration

```data
const Object Promise;
```

## Discussion

Discussion The asynchronous methods in CloudKit JS return a Promise object that resolves when the operation completes or is rejected due to an error. For a description of the Promise class returned by these methods, go to Mozilla Developer Network: Promise.
