Its a problem because if using promises as a return value for generic reusable functions, one should always know which methods can be used. And so if .done is not in spec, nobody should use this implementation for such case.

We have "core.js" which is a bare bones Promises/A+ implementation. index.js then contains extensions to that and is a super-set of the extensions provided by ES6 promises. https://www.promisejs.org/ has recently been updated to make clear that promise.done is non-standard. .done() is also implemented by the majority of popular promise libraries. This library could possibly use improved documentation though.

Other methods to be aware of:

Promise.from and Promise.cast are also unlikely to be part of the ES6 standard and will likely be deprecated from this library at some point. Promise.cast was briefly in the spec which is why it got added here.

Promise.denodeify and Promise.prototype.nodeify are not and will not ever be part of the ES6 standard, but they are going to remain in this library as they are necessarily for the library to be practical/useful in node.js

Thanks. This is something one should read in the first place...

These functions are marked with "Non Standard" in the README, closing.
