This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. universalify exports fromPromise as a function
  2. fromPromise wraps an async function to return a promise when called without a callback
  3. fromPromise delivers resolved value to a trailing error-first callback
  4. fromPromise delivers rejection error to a trailing error-first callback
  5. fromPromise propagates rejection when invoked as a promise without a callback
  6. fromPromise passes all arguments correctly to the wrapped function in both promise and callback modes
  7. fromPromise preserves the function name and this context
