Eta reduction and eta expansion are terms you might encounter when working with Haskell or functional programming. These concepts are rooted in lambda calculus and are essential for understanding how Haskell functions can be simplified or transformed. By learning about eta reduction and expansion, you can write cleaner, more concise code and better understand how…

A binary function in Haskell is a function that takes two arguments and returns a result. In Haskell, functions are inherently curried, meaning a binary function can be thought of as a function that takes one argument and returns another function expecting the second argument. Characteristics of Binary Functions in Haskell This means: 2. Curried…

In Haskell, type synonyms are a way to create new names for existing types, making code easier to read and understand without introducing new types or changing the underlying data structure. Type synonyms are especially useful for simplifying complex type definitions, improving code readability, and providing meaningful context for types in your code. This article…

In Haskell, types and typeclasses are distinct but related concepts that play key roles in the language’s type system. Here’s a breakdown of their differences: Types A type in Haskell describes the kind of data a value holds. Types are used to enforce that functions receive and return values of expected kinds, ensuring type safety.…

In Haskell, a type constructor is a function that takes one or more types as arguments and produces a new type. Type constructors are similar to data constructors, but while data constructors create values, type constructors create types. They’re particularly useful for defining parametric types, which are types that take type parameters (such as lists,…
