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…

Tuples – Haskell
In Haskell, tuples are a powerful and versatile way to store and work with multiple values. Unlike lists, which hold elements of the same type, tuples allow you to combine values of different types within a single, fixed-size structure. This makes tuples especially useful for grouping related but distinct pieces of data, like coordinates, database…

Babel Fees
Babel fees on Cardano are an innovative mechanism allowing users to pay transaction fees in tokens other than ADA, the native currency of the Cardano blockchain. This feature is particularly useful in cases where users hold assets or tokens but lack the required amount of ADA to cover transaction fees. Babel fees introduce a way…

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…
