Prefix Functions – Haskell
In Haskell, prefix functions are functions that are written before their arguments, as opposed to infix functions, which are written between their arguments. Most functions in Haskell are prefix by default. Key Points About Prefix Functions in Haskell Example: 3. Higher-Order Functions: Functions like map, filter, and foldr are typically used in prefix form, as…

Infix Functions – Haskell
In Haskell, infix functions are functions that are written between their arguments, rather than before them (prefix functions). This notation is commonly used with operators, such as + or *, but any function that takes two arguments can also be used as an infix function. Infix notation can make code more readable, especially for functions…

List of Operators – Haskell
In Haskell, operators are an essential part of the language that make it both powerful and expressive. Whether you’re working with basic arithmetic, manipulating lists, or chaining functions, Haskell’s rich set of operators provides flexible ways to interact with different data types. In this guide, we’ll explore the major operators available in Haskell, grouped by…

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,…
