lmao

OOP vs FP is a fucking meme.

Some problems are more suited to one, or the other. Dogmatically following one paradigm just shows how fucking stupid you are.

Do I have to learn some advanced math before starting with haskell?

Why are you so upset, Sanjay?

but OP, Clojure is infinitely better.

>>57832576
My friend, i must disagree.

While Clojure is a great language, any layman can write it.
The same cannot be said for Haskell.

It truly is the language of the enlightened

>>57832641

Lisp has been around for 50 something years and people are still intimidated by it.

You might like Oz then

>>57832213
no, not at all. You only need a general intuition about how types work.

How is Haskell for programming?
I'm stuck with C# because uni requirements but I don't particularly enjoy it and am looking for a new language.

>>57830456
having used haskell, i assure you its neither simple nor fun

stateless code, pure functions, etc are goat, but some things just need state, imperative coding, etc

the way java 8 does it is perfect

It's a giant meme that you are unlikely to actually use.

There are pretty webframeworks to build real life business stuff.

>>57832213

> Not at all.

But you need to understand three main techniques before becoming productive.

> Higher order functions
> Lazzyness
> Pattern matching


Anddd I almost forgot the ...

> Monad

>>57833498


>> Higher order functions

Imagine you have a function that takes two arguments

> add x y = x + y

but you just wnat apply one argument.

> add 1

what is the result of (add 1)? It's ...

> add x = x + 1

The result is a funtion that now take just one remaining arument and adds +1 to it.

>> Lazyness

Lazyness is the opposit of strictness. A lazy expression just evaluats to the point where the result is determind. Than it stops and ignors the rest of the expression. E.g. the function take takes the first two elements of the list and returns them. The list [1..] is a infinit list. Starting at 1 and counting up to infinity. In a strict language the list needs to be evaluationed up to infinity before the function take could return the first to elements.

> take 2 [1..]

>> Pattern matching

You can deconstruct arguments like tupel, e.g. a is 1 and b is 2

(a,b) = (1,2)

One benefit of Haskell is security. You can write incredibly robust web servers in Haskell. Also great for proving properties about your program. Very useful if you want to guarantee your program does EXACTLY what you expect.

>>57834135
>One benefit of Haskell is security
Because no one knows it?

>>57833614
All those features seem retarded. And what's wrong with OOP? It's way more advanced than any model that came before it.

Why not just use a Struct with a 1D Array and a Stride

>>57835120
Erlang user here, pattern matching is pretty comfy, and you can do it on binaries/bitstrings too (in Erlang, idk about Haskell), so you can get bits 3-7 out of a bitstring without having to fuck around with bitwise operators. Another good thing about functional languages is that functions have no side effects, which means that writing parallel code is easier than in non-functional languages (I haven't written parallel code in non-functional languages yet tho, only in Erlang, so I'm not speaking from experience on both). I'm not saying it's better than OOP, but it has its uses and it's definitely not retarded.

>>57833369
Any suggestions for something that's not C#, Java or Python then?
I hear C++ is good.

>>57835377
I don't dislike C# I dislike the fact that it's limited to one platform.
In terms of actually programming it's reasonably simple I'm just more interested in something more useful.

Trying to program in C# on a linux machine is a giant pain in the ass.

This has to be bait.
I am not suggesting that Haskell is the correct way to do things but Java-style OOP is horrible.

I suggest you to take a look at how Go and Rust handle types.

Best book for Haskell then?

Because in func programming a function only takes inputs and returns outputs. You can't access things outside the scope of the function.

>>57838700
Fucking please. Bait? You're just oversensitive to the truth. Without OOP you don't have code reuse or polymorphism.

>Functional programming is an alternative to OOP
Functional programming is horrendous as fuck and gives no alternative to any OOP concept. Procedural programming is the only flawless paradigm.

"Learn You A Haskell For Great Good"

Literally like that with bad grammar and all. It's available for free on his website. It's really well written. It's the reference book for a Haskell course I'm taking in university.

never.
fp is how ivory tower mathematicians wish computers worked, imperative (plus awareness of concerns like locality) is how they actually do.

It has first class closures, but it doesn't have many of the other distinctive features of functional programming languages.

How is that a bad thing?

It has already in any serious front-end web development gig in 2016. I use OOP for backend/API crafting, but mostly as an organization tool rather than a coding paradigm.

FP would be bigger if F# and Haskell weren't such shit-baskets (still love Haskell).

Hipster elitist confirmed. This is why haskell is viewed as a big fucking impractical meme that NO ONE uses in the real world. You say you want OOP to die, yet you don't want common people to be able to use it?
