Just drop the static typing requirement, then. http://lambda-the-ultimate.org/node/2927#comment-43268. It’s clear when you look at the type of (>>=) :: m a -> (a -> m b) -> m b. I like to think of it this way: the top level program (main) is a value in the language and there is an interpreter in the runtime which traverses that value and executes IO actions along the way.

There is nothing else that I call “functional programming”. This is not to say that FP and OOP are somehow opposites either.

A further explanation: Running it on different inputs may, of course, yield different results though. I like a functional approach because I prefer the way of thinking and sense of security of immutability and pure functions. Aren’t you tired of preaching to the converted and trolling by now? I think what you're comparing here is a structured programming / procedural approach vs a functional one. To do so is trivial yet would be revealing: the imperative code, to the consumer of the function, is indistinguishable from the functional code. Your last paraghraph is a classic case of strawman argument. OOP isn’t in any way more natural to computers than functional code, whatever the definition of “functional”. In the 1970s, Pascal was developed by Niklaus Wirth, and C was created by Dennis Ritchie while he was working at Bell Laboratories. In JavaScript, besides supporting imperative programming, you can also write declarative (functional) programming at the same time by using some of those function map, reduce, filter. And the really powerful abstractions simply do not work without function programming’s purity, and a bit of maths. Processors speeds are no longer growing at the rate we've grown accustomed to. And by using them, you are extremely explicit about what is happening: if you use map, you are doing that and only that. Your problem is not with FP, but with high level languages in general. My verbose middle comments contained some errors (perhaps due to exhaustion made after midnight at end of 18 hour work day in an Asian internet cafe with multiple patrons simultaneously loudly singing different songs for hours, also fighting an amoeba taking flagyl, and I have 1 eye). Also, replace “or case classes” with the more general “or subtypes”. It's fine that the lambda closes over itemToSearch. If I accepted your notion of imperative, then everything is imperative, and there is no such thing as pure code. Thus this is a hack to claim[1] that side-effects don’t matter to purity, by assuming that the World input type of the of IO action function is computable, but never having the compiler check its infinite structure. In imperative programming you change state by changing a variable. Sure, certain languages are better suited to certain styles of programming, but it’s important to differentiate on essentials and not mere aesthetics. Scala makes it easier to lie about purity, because its type system does not even check for purity, so any kernel function that interacts with the world, is impure.

In computer science, functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data.”. Let me repost that reply with unintended html tags removed, because wordpress butchered it and big chunks were missing: The morphism functions are not required to execute in the order given by the nested ‘bind’, because they are pure and due to caching of function return values (i.e. Heck one guy, maybe two or even more, have been using it in production for many years! A lot of pieces of Haskell that come from its roots in mathematics are incredibly useful and not hard to understand. The problem here is that the World state includes time, and thus it never has the same state.

*/, JavaScript Katas: Seconds To Minutes And Hours. The loop does break referential transparency. Agreed. And precisely because time is precious, I’m not going to waste it on platitudes and wankery. The poem may be beautiful, but they can’t read it. But that doesn’t make it the only way, or even the best way. You failed to argue as to why my conversation has nothing to do with rational thought process. You know objects!” But it’s bollocks. Thus the composition is pure, not imperative. They don't only 'do' the same thing, they are indistinguishable.
