When we start to accumulate functions that all work on a given datatype, we end up creating a bunch of boilerplate code in almost every function to handle the changes we need to make to our records’ values. This can lead to not only undesirable boile…

Using Naive JS: const {modify, get} = require('crocks/State'); const K = require('crocks/combinators/constant'); const B = require('crocks/combinators/composeB'); const assign = require('crocks/helpers/assign'); const prop = require('crocks/Maybe/pro…

We have the ability to select a single random card from a pile of twelve cards, but we would like to pull a total of nine. Not only that, we would like to match the same transition functions we have been writing all along. Lucky for use there are thr…

Lifting Now, let's review map from another perspective. map :: (T -> R) -> [T] -> [R] accepts 2 parameters, a function f :: T -> R and a list list :: [T]. [T] is a generic type paramterized by T, it's not the same as T, but definitely shares s…

In functional programming, a monad is a design pattern that defines how functions, actions, inputs, and outputs can be used together to build generic types,[1] with the following organization: Define a data type, and how values of that data type are…

1. Functional programming treats computation as the evaluation of mathematical and avoids state and mutable data. Scala encourages an expression-oriented programming(EOP) 1) In expression-oriented programming every statement is an expression. A state…

Functions in Java Prior to the introduction of Lambda Expressions feature in version 8, Java had long been known as a purely object-oriented programming language. "Everything is an Object" is the philosophy deep in the language design. Objects a…

background In pursuit of a real-world application, let’s say we need an e-commerce web applicationfor a mail-order coffee bean company. They sell several types of coffee and in differentquantities, both of which affect the price. Imperative methods F…

In computer science, functional programming is a programming paradigm, a style of building the structure and elements of computer programs, that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It is a…

In this blog post I will talk about the changes coming in Angular 2 that will improve its support for functional programming. Angular 2 is still in active development, so all the examples are WIP. Please focus on the capabilities and ideas, and not t…
