Given below code, I need to reuse functionality from innerFunc1 and innerFunc2 in innerfunc3, but I am not sure, how innerFunc1 and innerFunc2 can be accessed i
I'm learning React and TypeScript. For sake of practise, I've tried to create a calculator design by merging two arrays to map a single array onto the grid (dis
So I have written a method to count the number of lines in a file in ZIO. def lines(file: String): Task[Long] = { def countLines(reader: BufferedReader): Ta
I'm trying to achieve this using only functional programming constructs (Streams, Collectors, lambda expressions). Let's say list is a String[]: {"Apple", "Sa
I want to use a function which accepts some arguments in a toolz.pipe, but data input is a tuple. I know how to solve it, but I think there must be some solutio
In Haskell there is a simple list function available iterate :: (a -> a) -> a -> [a] iterate f x = x : iterate f (f x) In python it could be implemen
Let's say I have a function foo: def foo(A, B, C) A + B + C end And I call it like this, with only the last parameter changing: foo("foo", "bar", "123") foo("
Let's say I have a few primitives defined, here using javascript: const TRUE = x => y => x; const FALSE = x => y => y; const ZERO = f => a =>
I was having a look at the Arrow library found here. Why would ever want to use an Option type instead of Kotlin's built in nullables?
One advantage of pure functions is that their inputs fully determine their outputs, allowing the result to be cached for later use. However, I don't see how thi
I have an instance of Num for a type I created called Vec: instance Num Vec where (+) (Vec x) (Vec y) = Vec (zipWith (+) x y) And I am trying to write a test
I'm having some trouble with the test cases for Project Euler #1 on HackerRank and was hoping someone with some JS experience on HackerRank could help out. B
We have a microservice which enables consumers (indirectly) to query a database, where we have our own logic to limit what consumers can do with the queries. Wh
I came across a problem that required iterating over an array in pairs. What's the best way to do this? Or, as an alternative, what's the best way of transformi
