- // Transparently applies callbacks to values and/or promises.
- // description:
- // Accepts promises but also transparently handles non-promises. If no
- // callbacks are provided returns a promise, regardless of the initial
- // value. Foreign promises are converted.
- //
- // If callbacks are provided and the initial value is not a promise,
- // the callback is executed immediately with no error handling. Returns
- // a promise if the initial value is a promise, or the result of the
- // callback otherwise.
- // valueOrPromise:
- // Either a regular value or an object with a `then()` method that
- // follows the Promises/A specification.
- // callback: Function?
- // Callback to be invoked when the promise is resolved, or a non-promise
- // is received.
- // errback: Function?
- // Callback to be invoked when the promise is rejected.
- // progback: Function?
- // Callback to be invoked when the promise emits a progress update.
- // returns: dojo/promise/Promise
- // Promise, or if a callback is provided, the result of the callback.
