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…

How long does it take to learn the most popular programming languages?
The time it takes to learn a popular programming language depends on factors like the learner’s prior experience, the language’s complexity, the level of proficiency desired, and the resources available for learning. Here’s a general guide for how long it might take to become comfortable with some of the most popular programming languages, assuming regular…

Space Age 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 Given an age in seconds, calculate how old someone would be on: So if you were told someone were 1,000,000,000 seconds old, you should be able to…

Case Expressions – Haskell
In Haskell, case expressions are a powerful tool for making decisions based on the structure and values of data. Case expressions allow you to match patterns, deconstruct data, and define behavior based on different scenarios, all within a single, flexible construct. This makes them especially useful in functional programming, where immutable data and pattern matching…

Bindings – Haskell
In Haskell, bindings are a foundational concept that allows you to give names to values, expressions, and functions. Unlike variables in imperative languages, bindings in Haskell are immutable by default, meaning once a name is bound to a value, it cannot change. This immutability leads to safer, more predictable code, which is at the heart…

Understanding the Type System in Haskell
Haskell is known for its strong and expressive type system, which serves as both a powerful tool for error-checking and a guide to writing clear, maintainable code. Haskell’s type system helps you define precisely what kinds of data your functions expect, process, and return, ensuring that code behaves as intended while eliminating many types of…
