I assume it has been pointed out before that Underscore/LoDash have popularised their own "chain" function/concept? http://underscorejs.org/#chaining Hopefully it's distant enough from Promise-world to alleviate most confusion, but I thought I'd point it out for completeness. On the flatMap name, as a Scala developer, I find it quite conveniently describes the "flattening" nature of the operation, although it only really works thanks to the parallel with map: M[A]#map(f: A => B): M[B] M[A]#flatMap(f: A => M[B]): M[B] (not M[M[B]] as it would with map - hence the "flat") But given that 'then' is a sort of a mix of map/flatMap (and flatThen is terrible), I don't think there is an obvious parallel currently. Seeing as flatMap/chain is being discussed though, have there been plans to add a map method on Promises (that would map to a new Promise without unwrapping returned promises)? And have there been any discussion to add other monadic types to ES, eg Option/Maybe, Try, etc, or to make existing types support more monadic operations, eg Array.prototype.flatMap (or "chain"?). Thanks, and sorry if this has been discussed before (is there any way to "catch up" on such topics if it has, short of reading piles of minutes?).
