Operator vs. Function – Haskell
In Haskell, both operators and functions are used to perform operations on values, but they differ in their syntax and sometimes in how they are used. Here’s a breakdown of the differences: 1. Syntax and Notation Example: 2. Infix vs. Prefix Application Example: 3. Custom Operators vs. Regular Functions Example of a Custom Operator: 4.…

Steps a Develop Should Take to Create a Function in Haskell
Creating a function in Haskell involves a few key steps, each of which helps ensure that the function is well-defined, readable, and functional. Here’s a step-by-step guide a developer should follow when creating a function in Haskell: 1. Define the Function’s Purpose Example: Create a function double that takes an integer and returns its doubled…

Guards – Haskell
Haskell provides several features that allow for elegant and expressive code. One such feature is guards, which give you a powerful way to express complex conditional logic in a clean and readable manner. Guards allow you to write functions that branch based on different conditions, offering a clearer alternative to multiple if-else statements. In this…

Recursive Functions – Haskell
Haskell encourages a different style of thinking compared to imperative languages. One of the most powerful techniques in Haskell is recursion. The term recursive refers to a process or function that repeats itself in a self-similar way. In programming, recursive functions are a fundamental concept that allow you to define solutions by breaking down a…

Pattern Matching – Haskell
Haskell offers several elegant and powerful features that allow for concise, readable code. One of the most notable features is pattern matching, a technique that lets you match values and structures directly, making your code more intuitive and expressive. In this article, we’ll explore the concept of pattern matching in Haskell, explain how it works,…

List Comprehension – Haskell
Haskell, a purely functional programming language, is well known for its elegant and expressive syntax. One of the features that contributes to its expressiveness is list comprehension. List comprehensions in Haskell provide a concise and powerful way to create and manipulate lists by specifying rules for constructing elements. In this article, we’ll explore what list…

Unique Syntax of Haskell: Exploring Key Language Features
Haskell is a purely functional programming language known for its elegant and expressive syntax. While many programming languages share common structures and conventions, Haskell has several unique syntactic elements that make it stand out. From the use of apostrophes in function names to its strict conventions around type casing, Haskell’s syntax is designed to enhance…

The Difference Between Strict and Lazy Functions in Haskell
Haskell is known for its lazy evaluation model, a distinctive feature that sets it apart from most other programming languages. In Haskell, computations are delayed until their results are actually needed. This concept of laziness can be contrasted with strict evaluation, which is the default in many other languages where expressions are evaluated immediately when…

List of the Basic Functions in Haskell [w/ Examples]
Haskell is a functional programming language known for its high-level abstractions, immutability, and strong type system. While its elegance and power can seem intimidating to beginners, it comes with a rich set of basic functions that make it easier to get started with. Whether you’re performing simple arithmetic, manipulating lists, or exploring higher-order functions, understanding…
