I want to learn a functional language that will be good for building web applications in the future. I am choosing between Clojure and Haskell. Which one is a better choice for my purpose?

Trying to learn Haskell. I am trying to write a simple function to remove a number from a list without using built-in function (delete...I think). For the sake of simplicity, let's assume that the input parameter is an Integer and the list is an Integer list. Here is the code I have, Please tell me…

I'm trying to use Haskells Data.Heap module, but I'm incapable of even using it with integers. The only heap I've been capable of using is "empty", which does not take any arguments.
Later on I'll figure out how to instance for my needs, but for now I'd be glad if I was even able to test it with…

There has been some intermingling of Scala and Haskell communities, and I have noticed now and then people commenting on stuff that's supposed to be easy in Haskell and hard and Scala. Less often (maybe because I read Scala questions, not Haskell ones), I see someone mentioning that something in Scala…

I have problems installing ghc-mod on my linux machine. cabal worries about "happy" not being available in versione = 1.17:

fibs :: [Int]
fibs = 0 : 1 : [ a + b | (a, b) <- zip fibs (tail fibs)]
This generates the Fibonacci sequence.
I understand the behaviour of the guards, of :, zip and tail, but I don't understand <-. What is it doing here?

This question has been going through my mind quite a lot lately and since I haven't found a convincing answer to it I would like to know if other users
of this site have thought about it as well.
In the recent years, even though OOP is still the most popular programming paradigm, functional programming…

I recently started studying functional programming using Haskell and came upon this article on the official Haskell wiki: How to read Haskell.
The article claims that short variable names such as x, xs, and f are fitting for Haskell code, because of conciseness and abstraction. In essence, it claims…

When would you NOT want to use functional programming? What is it not so good at?
I am more looking for disadvantages of the paradigm as a whole, not things like "not widely used", or "no good debugger available". Those answers may be correct as of now, but they deal with FP being a new concept (an…

It seems to me that functional programming is a great thing. It eliminates state and makes it much easier to automatically make code run in parallel.
Many programmers who were first taught imperative programming styles find it very difficult to learn functional programming, because it is so different…
