This project hosts practical algorithms to arrange asynchronous operations on node.js and browsers, and two specialized implementations of promises, if you need some advanced functionality.

This project provides a complete algebra over promises, and helpful utilities. Bundled deferred objects implement fast easy-to-debug promises with an extended API and functionality, including cancellable asynchronous operations, and progress signals. They are intentionally relax some Promise/A+ tenets to reduce code, and improve performance, e.g., by avoiding time-outs, which is important for client-side applications. Full interoperability with built-in ES6's Promise is provided out of box.

All algorithms (and specialized promises) can inter-operate with other implementations of promises. Everything works well with "foreign" promises as long as they are then()-able (an object or function that defines a then method).
