Since both Chrome and FIrefox have plans to support Promises, feel free to suggest any changes to `es6-shim` which would improve compatibility. It looks like that at the moment the `es6-shim` implementation is more spec-compliant than either of the shipping implementations? In particular, we support subclasses. At the moment we don't do any feature tests beyond "does Promise exist in the global environment". For Map and Set we actually do some very specific bug-based tests to workaround old shipping implementations that aren't spec-compliant. So I'd also love to hear specifically about any bugs or missing features in your shipping implementation so that we can feature-test and workaround them. Finally, I have started `prfun` (https://github.com/cscott/prfun) as AFAIK the first "es6-compatible" promise package. That is, it assumes the presence of basic ES6 spec-compliant Promises and concentrates on adding features on top of that, using only the published API. It includes an implementation of `Promise.bind` using subclasses, in ES5-compatible syntax. It has a rather extensive test suite, borrowed from `bluebird`, `when`, and `q`. Feedback on `prfun` (including suggestions for better names!) is invited. --scott _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
