Or, much more simply: * Future.accept takes a Foo and returns a Future<Foo>. * Future.resolve takes either a Foo or a Future<Foo>. In either case, it returns a Future<Foo>. * In Future.then(cb), the cb is expected to have the signature (Foo -> Future<Foo>). It has some extra magic that allows you to return a plain Foo, and treats it the same as if you returned a Future<Foo>. Effectively, this means that it passes the return value through Future.resolve() to normalize it into a Future<Foo>. * You can totally make nested Futures deliberately by doing something like "Future.accept(Future.accept(5))". ~TJ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
