The purrr package provides a reduce function which has a concise syntax:

Angular's promise library $q is based on kriskowal's Q library (which has a richer API, but contains everything you can find in $q). Q's API docs on GitHub could prove useful. Q implements the Promises/A+ spec, which goes into detail on how then and the pro...
