Functional Programming literally has 'fun' in the title; OOP is one letter away from 💩. I rest my case.5

Interviewed a dev for a junior role earlier this week...my first question:
const numbers = [0.1, 0.2, 0.3];
let sum = 0;
for (i = 0; i < numbers.length; ++i) {
setTimeout(() => {
sum += numbers[i];
}, 0);
}
// Refactor the preceding code so that the following returns true.
console.log(sum === 0.6);

He had no idea where to even start, so I asked him to walk through the code with me line by line, he couldn't get past line 1 - literally didn't know what an array was... I walked through the code with him and he just started to look more and more lost.
I didn't even bother with the rest of my questions on OOP, FP, etc...
Am I really expecting too much of somebody that claims to have 2 years practical experience in JavaScript, jQuery, Angular, and PHP?
Do you think this is a problem a junior dev should be able to solve...even if it takes some hand-holding?64 -

Don't get me wrong, I like funcional programming, but this smug „This would neeever happen with FP“ bullshit really gets on my nerve and kind of turns me off the idea of ever wanting to work with FP programmers.
It's just another paradigm, it's still possible to write unmaintainable fuckugly crapcode with functional programming.
And it is still very possible to write beautiful, clean, well maintainable code with OOP. Get over yourselves and understand that it's a tool and not a religion, and a good dev should know when to pick which tool for which job without childish notions of intellectual superiority.5 -
One of the biggest barriers to the wide(r) scale adoption of functional programming languages like Haskell, F#, and Scala is how snooty and condescending your average FP developer is. And beginner-unfriendly.
Ask them a question about an intermediate topic (in my case, the Free monad) you're likely to get a whole torrent of category theoretic rubbish in return.
This is a common pattern I see when "experts" answer questions.
Now, it didn't bother me much because I've studied a fair amount of category theory and can usually follow such answers, but, for the sake of the general case, I'd like to shove these rules into the heads of everyone writing an answer to a question (not just FP):
1. If you can't illustrate a concept clearly without going into verbal diarrhoea with phrases like "monad homomorphism" and "just a monoid in the category of endofunctors" then you clearly haven't understood it properly (unless, of course, the answer absolutely requires it). An answer is not the place to show off your knowledge of a topic.
2. Please remember that everyone was a beginner at some point. Including you. Understand that some concepts can be extremely frustrating at first and yet incredibly simple after you grok them (eg. monads).
3. If the person asking the question is a beginner, using complex concepts in an answer just because it's a more "elegant" way to explain it doesn't really help them. They are more likely to get confused and drop the topic.
(Kudos to those people who give highly relevant, insightful, simple, and intuitive answers, you guys are the best).2 -
Dear Chrome/firefox developers,
If someone presses the back button after they click on a link it means don't load that page and not go back to previous page.4 -

It's truly amazing how much a single line of perl can do. Such a time saver.
I only wish that I could understand what it does two days later.1 -
"I'm almost done, I'll just need to add tests!"
Booom! You did it, that was a nuke going off in my head.
No, you shouldn't just need to add tests. The tests should have been written from the get go! You most likely won't cover all the cases. You won't know if adding the tests will break your feature, as you had none, as you refactor your untested mess in order to make your code testable.
When reading your mess of a test case and the painful mocking process you went through, I silently cry out into the void: "Why oh why!? All of this suffering could have been avoided!"
Since most of the time, your mocking pain boils down to not understanding what your "unit" in your "unit test" should be.
So let it be said:
- If you want to build a parser for an XML file, then just write a function / class whose *only* purpose is: parse the XML file, return a value object. That's it. Nothing more, nothing less.
- If you want to build a parser for an XML file, it MUST NOT: download a zip, extract that zip, merge all those files to one big file, parse that big file, talk to some other random APIs as a side-effect, and then return a value object.
Because then you suddenly have to mock away a http service and deal with zip files in your test cases.
The http util of your programming language will most likely work. Your unzip library will most likely work. So just assume it working. There are valid use cases where you want to make sure you acutally send a request and get a response, yet I am talking unit test here only.
In the scope of a class, keep the public methods to a reasonable minimum. As for each public method you shall at least create one test case. If you ever have the feeling "I want to test that private method" replace that statement in your head with: "I should extract that functionality to a new class where that method public. I then can create a unit test case a for that." That new service then becomes a dependency in your current service. Problem solved.
Also, mocking away dependencies should a simple process. If your mocking process fills half the screen, your test setup is overly complicated and your class is doing too much.
That's why I currently dig functional programming so much. When you build pure functions without side effects, unit tests are easy to write. Yet you can apply pure functions to OOP as well (to a degree). Embrace immutability.
Sidenote:
It's really not helpful that a lot of developers don't understand the difference between unit, functional acceptance, integration testing. Then they wonder why they can't test something easily, write overly complex test cases, until someone points out to them: No, in the scope of unit tests, we don't need to test our persistance layer. We just assume that it works. We should only test our businsess logic. You know: "Assuming that I get that response from the database, I expect that to happen." You don't need a test db, make a real query against that, in order to test that. (That still is a valid thing to do. Yet not in the scope of unit tests.)9 -
Scala's default Seq is MUTABLE. Why the fuck do I want mutability in my functional scala code!?
Now I have to riddle my code with imports to scala.collection.immutable.Seq which looks just ugly.

Pet peeve: the claim that static typing prevents errors.
Today I worked on a C# project that's a mess of nulls, side-effects, inferences, and race conditions. Then I went back to a JS project that's twice the size but written in a clean, well-tested, FP style and currently has fewer than 10 issues logged.
Look, I get that there are upsides to static typing, and I'm open to introducing typescript or flow for our JS code.
I just can't stand the faux-concern from the static typing dingleberries when they are the ones who produce these horrendous lumps of unmaintainable shit, and the JS/Python/Ruby/etc people are over here quietly reinventing functional programming and code modularity.11 -
Unpopular opinion:
Coding on paper exams actually do help at beginner stages of learning to code.
It makes you at least think how to write things simply, without overthinking the problem, makes you familiar with semicolons (so all you stupid fks wont complain that it has taken you 2 hours to find missing semicolon (actually, who has ever encountered that problem, besides memes?)), makes you learn the syntax, just many benefits that spoiled OOP/FP starting kids cant see, because they relied on autocomplete so much.
God, I hate people who are trying to render things stupid just because they can't see the fking point -.-'
Losing my mind about who goes into "programming" and who calls himself "developer" is just fueled by that.11 -
All code and no tests makes a software buggy, hard to maintain and a pain in the ass to work with.3

I started making a library to get to know TypeScript. 4 days into the commits and I don't know if I made the best choice or the worst choice. I MEAN WHY CLASSES!! JAVASCRIPT IS MORE A FUCNTIONAL PROGRAMMING LANGUAGE THAN AN IMPERATIVE PROGRAMMING LANGUAGE! I DONT WANT TO NEW UP! I DONT WANT THE DEVELOPERS TO NEW UP! WHERE ARE THE DESIGN PATTERNS! I CANT FUCKING FIND IT!!4

I am thinking about picking up a functional language. Currently I use Kotlin (and I fucking love that language) but I have to admit that it's support for functional programming is limited.
But I think their lies a certain beauty in fp and I want to do some project with it.
The 2 main problems are:
1. I have no experience in functional programming. I have no clue how to structure my program (potantialy without oop) and write clean testable code.
2. I don't know what language to use. Scala seems great since it has good IDE support and I like the Java ecosystem and Haskell seems to have more beauty but is missing that IDE support and it is very unfamilar for me.
So what do you guys think I should pick up? And how do I learn to write good software with it?17 -
Hey, dfox & trogus
How about some Haskell/Scala/F#/OCaml/Clojure/Scheme swag? For example, I'd love a Haskell-caped devDuck.
Show us functional programmers some love pls ;_;2 -
3 weeks into Elixir and Functional programming in general. Words can't describe how much I love developing software with this toolset. Can this get any better ?4

Flame war:
Best functional language + eco system for web dev -
F#, Haskell, Scala, elixir, other?
Same for scientific/mathematical simulations?9 -
Just starting with scala. And while I dig the more functional programming approach I am having the hardest of times dealing with naming higher-ordered functions, in my case a function returning another function.
Started out as `foo`, went through quite a lot of changes, and now it has become the beast: `createReplacePriceByPassengerConfigurationMapperFunction`. It won't stay that way but: GOSH! Naming. It's hard! Or I might as well suck at functional programmig. It's not like that these two things are necessarily mutually exclusive. -
Smalltalk, the language that keeps popping up in articles I read about nice languages and seems like the real underdog that's gone under the radar now that FP has taken hold. Must give it a go.4

I'm a full stack web dev (LAMP, MEVN), not a sys admin. Besides complete control of my os, are there any benefits to a Linux-based os like arch or ubuntu? I've played around and set up both in VMs, but I'm struggling to find a benefit that justifies the setup commitment.5 -
Finding it hard to focus. I'm into UI, backend, frontend, iOS... Exploring FP. We've just had our first child and I need to put my time and energy into what will a) provide healthy financial remuneration b) be more enjoyable than frustrating c) be relatively futureproof (if that's even possible). For some reason I have a huge distaste for JavaScript (as an ecosystem) which has led me to look into Elm. I've enjoyed Ruby but something in my mind tells me Functional programming is more logical for me. It's a whole new approach and skill to level-up on. I love programming my own back-ends, but for me, design is so important and I want to be part of the visual, tangible part that people interact with. I'm a one-man operation which means I do design, full stack Development, client liaison, financials, client acquisition. Freelancing is a double edged sword - I don't know when the next project will come, but I also need to focus on the projects I have without taking too much on. At times I think employment would be good, despite having it's on drawbacks which I read about repeatedly on here. Any advice?1

Just typed this into the Python interpreter and my whole system just froze. Guess I have to do a force shutdown.
x = list(range(1, 999999999))
So is there a way you can somehow configure your linux system such that the window manager/system is never out of memory or processor time? So that atleast I get can atleast kill the process which is freezing the system.5 -
Do you think, that its a good idea, to add FP-features like Map,Filter,Reduce to Stack or Queue datastructures, in the way, that they pop all elements?7

Why my friend learns new languages: will it get me a higher salary?
Why I learn new languages: work isn't challenging, I don't have any side projects, don't feel like binging anime...
Just started learning Scala to once again try to pick up FP paradigm.
I'm also thinking it may be better for understanding algorithms?
Yes I know I'm late to the party -
Was attending a session on a module written on F#. The trainer justified the choice of F# saying "This module uses lot of calculations and so we use functional programming". She also shows big exponential value expression(apparently not written functionally). Have I not understood the premise of FP or is she just rambling?1

Why are we still on the object oriented bandwagon? Having started to learn FP, I feel that we need to be transitioning to FP stacks way more faster given it's huge advantages.
I'm really interested in knowing your opinion2 -

Learning and working on a project built with purescript (fp).
Wrapping up my brain to think functionally and understanding it to implement is like rewiring my brain. I sometimes have to literally sleep on it, only to go through the concepts again the next day to get a little more insight than the day before 😝
Functional concepts are abstract af, but it sure does give you wings to liberate you from conventional way of things. -
Python's wonderful `reduce` for the win. Using it makes you feel like a FP pro, but also makes code really unreadable sometimes. (Sigh)

As a junior, mild and hacky OOPer/TDDer I once worked with an architect who professionally introduced me to functional programming obsession and TDD fanatism.
I'm not a junior anymore, I have less dev friends too, but now none of them has unforeseen side effects or unexpected behaviour. -
FP/Math guy here. Just opened Ionic docs because... anyways. Why am I getting an unusual amount of red flag raising here? Even scared to go on.

I've done a really bad thing.
I've used someone's code licensed on CC without crediting the author... two times...
I know this is super bad, but you know what I don't understand?
Okay, I've done bad, year ago and a few months ago. Three years ago, when I was 13, I've tried to be a team leader, funny, right? Well, shit started happening, met some people who like the same things in It as I do, and started talking with them, improving the relations. The shit went down, lies (mainly produced by me to have a shield against them) and other stuff. I've done a lot of bad things. Okay, I understand it, you may not trust me that I'm not doing it anymore. BUT, they're not the only things I've done. Here's what I don't understand. Used someone's code on CC license twice, I could even sold it but they say I'm a thief and I lied to them few times, but I was more a kid than I am right now. You know what I mean, right?
But I've done also some cool things, I guess. I've done the free logo for them when they were on Hackathon, I've 'made' a font (added more glyphs), I've made website template and I'm moving into FP territory and stuff. Shall we look at people, just by keeping in mind a few bad things? Ehh... I'm tired of it....1
