Prelude Module – Haskell
The Prelude module in Haskell is the foundational collection of functions and definitions that automatically loads with every Haskell program. It provides essential functionality for handling data types, performing basic operations, and manipulating lists, allowing programmers to get started without needing to import additional libraries for fundamental tasks. This article explores the Prelude module, highlights…

Function Composition – Haskell
Function composition is one of the core concepts in Haskell and functional programming in general. It allows you to build complex functions by combining simpler ones, much like chaining steps in a sequence of transformations. In Haskell, function composition not only makes code more concise but also more expressive and modular. This article will explore…

Lambdas – Haskell
Lambda expressions, also known as anonymous functions, are a core feature of functional programming languages like Haskell. They provide a concise way to create functions without naming them, which can be incredibly useful for short-lived functions or when you need to pass a function as an argument. In this article, we’ll dive into what lambdas…

The Haskell Advantage: Why Learning Functional Programming Opens Doors to Cardano
With the rapid growth of blockchain technologies, developers are seeking ways to stand out and make meaningful contributions to innovative platforms like Cardano. Unlike other blockchains, Cardano is unique in its choice of language and programming principles: it’s developed in Haskell, a functional programming language known for its precision, safety, and mathematical rigor. If you’re…

The Differences Between Imperative and Functional Programming Languages
Programming languages are often categorized based on their approach to solving problems and organizing code. Two of the most popular paradigms are imperative programming and functional programming. While both paradigms aim to help programmers build efficient and effective solutions, they differ significantly in their underlying principles, syntax, and style. This article explores the key differences…

Higher-Order Functions – Haskell
In Haskell, functions are more than just sequences of instructions; they are fundamental building blocks that can be manipulated like any other data. One of the most powerful concepts in functional programming, especially in Haskell, is the higher-order function. Higher-order functions are functions that can take other functions as arguments or return functions as results.…

Curried Functions – Haskell
Haskell brings a unique and powerful approach to handling functions: it treats all functions as curried functions by default. This concept, coupled with partial application, allows for more modular, reusable, and flexible code. In this article, we’ll explore what curried functions and partial application are, why they matter, and how they can be used effectively…

Pangram Problem – Haskell [Problem Solved]
Background This problem comes courtesy of the great folks over at Exercism. I highly recommend jumping on their Haskell track to apply your knowledge of Haskell. The Problem Your task is to figure out if a sentence is a pangram. A pangram is a sentence using every letter of the alphabet at least once. It…

Recursion – Haskell
Recursion is a concept in programming where a function calls itself in order to solve a problem. Recursive functions are useful when a task can be broken down into similar subtasks, allowing the function to repeat its own logic until it reaches a stopping point (called the base case). In Haskell, a functional programming language…

Why do we always split a list into a head and a tail in Haskell?
In Haskell, lists are defined recursively as a head (the first element) and a tail (the remainder of the list). This structure allows for easy and efficient pattern matching, recursion, and functional operations on lists. Here’s why we often split lists into head and tail: 1. Simplicity of Recursive Definitions Example: Sum of a List…
