spromise is a tiny, standards‑compliant implementation of the Promises/A+ specification for JavaScript, providing a lightweight, high‑performance promise library that works in both Node and browsers. It offers the usual static helpers (​`defer`, `resolve`, `reject`, `when`, `all`) and instance methods (`then`, `done`, `fail/catch`, `always`, `delay`, etc.) and is aimed at developers who need a minimal, interoperable promise solution compatible with other libraries such as jQuery’s Deferred.
