You might have heard of RxJS, or ReactiveX, or reactive programming, or even just functional programming before. These are terms that are becoming more
In the previous post, I showed how to manually rewrite a Python function into “combinator form”, and then apply YC to it, to get a serialisable version of the original function. In this post, I show…
When I recently asked a roomful of developers, if there’s anyone who had learned a new language this year, only very few hands went up. A year ago today, that would have been me in the audience, keeping my hands down. … And it was like this, until Haskell ruined it for me!
Once we were over the infamous Haskell learning-curve, we began looking for functional programming, immutability, and types everywhere! Given that one-third of our code runs in the browser (via Angular v1 — for now!), it is only a matter of time before we make the switch to typed-FP for front-end development as well.

The Computational Chemistry Comparison and Benchmark Database (CCCBDB) contains links to experimental and computational thermochemical data for a selected set of gas-phase atoms and molecules as well as tools for comparing experimental and computational ideal-gas thermochemical properties.
When it comes to applications intended to last, I think we all want to have simple code that’s easier to maintain. Where we often really disagree is how to accomplish that.
I sat in a coffee shop reflecting on my journey in Haskell today. It was spurred on by briefly seeing the whole “monads are pipes” thing and some responses to it. I don’t involve myself in these…
Telos Functional and Integrative Medicine, La crosse mission is to provide customized and personalized care for each of our clients. We achieve this by incorporating a systems biology framework into our medical practice. The goal of functional medicine is to address the root causes of each person's sickness to discover how and why an illness develops and to restore health. We accomplish this by applying a Systems Biology approach to our practice of medicine. In alliance with our clients, we succeed by leveraging leading-edge science to decipher the complex interaction of our clients' genomes and their unique epigenetic responses to exposures over time.
This concepts are very used nowadays on functional programing, but because of the heavy mathematical background, sometimes it may be confusing to understand all the definitions. In this post I’ll try…
React's future is going to be more functional, and less OOP. What if that future is already reality? How would it look like? React's foundations are reactive...
Functional programming is the mustachioed hipster of programming paradigms. Originally relegated to the annals of computer science academia, functional programming has had a recent renaissance that is due largely to its utility in distributed systems (and probably also because “pure” functional languages like Haskell are difficult to grasp, which gives them a certain cache). Stricter functional programming languages are typically used when a system’s performance and integrity are both critical — i.e. your program needs to do exactly what you expect every time and needs to operate in an environment where its tasks can be shared across hundreds or thousands of networked computers.
Who knows — probably? That’s not the point of this article – I am not going to talk about what Elm could be, I am going to tell you what it is today. Elm is a functional language that compiles to…
Redux-Observable is a middleware for Redux which handles cancellation and many other asynchronous side effects by using reactive programming. … RxJS and Most.js are two libraries for reactive programming with which you can handle streams of actions in different ways. … In the following examples, Most.js will be used.
Looking at the teaching of science and the importance language plays. Study shows how a taxonomy of language is built by students. Exploring how students then used language as a resource to unlock meaning and to decide upon an appropriate. answer. Conclusion focused on the implications for teaching science.
This article uses a high school science class to see how language was used to connect theory and practice. It draws on classroom data analysed from a functional linguistic perspective, exploring the nature of science as a socially constructed practice.
I'm a huge fan of typed functional programming. I've also been working with JavaScript and Node.js for a lot longer than I've been working with languages like Haskell. So when we were building out the server for Ellie I wanted to use what I've learned studying functional programming while sticking with a language and platform familiar to web developers. A huge theme of my programming practice so far has been understanding how to represent effects like database calls and network requests in a way that is still testable.
Reactive streams are a unified way of dealing with asynchronous events in JavaScript. Learn more in this tutorial with RxJs examples that you can run & modify.
A library to deal with Immutable updates in JavaScript. Based on the famous lens library from Haskell. Wrapped in a convenient Proxy interface - yelouafi/focused
When looking for a new backend language, I naturally went from Python to the new cool kid: Go. But after only one week of Go, I realised that Go was only half of a progress. Better suited to my needs than Python, but too far away from the developer experience I was enjoying when doing Elm in the frontend. So I gave Rust a try.
Every day that I work in JavaScript-land, I stumble across a mixture of callbacks, promises or async/await. I have my own preferences in how I like to handle async code, though sometimes I don’t have…
Purely functional code makes some things easier to understand: because values don't change, you can call functions and know that only their return value matters—they don't change anything outside themselves. But this makes many real-world applications difficult: how do you write to a database, or to the screen? In this screencast we look at one method for crossing this divide.
"Functional-Light JavaScript" explores the core principles of functional programming (FP) as they are applied to JavaScript. But what makes this book different is that we approach these principles without drowning in all the heavy terminology.
Functional mixins are composable factory functions which connect together in a pipeline; each function adding some properties or behaviors like workers on an assembly line. Functional mixins don’t…
Elegant, instructive examples of functional programming. Supposed to be fun, and teach important programming techniques and fundamental design principles. Traditionally appear in Journal of Functional Programming, and at ICFP and affiliated workshops.
With all the hubbub over functional programming in JavaScript, you might be confused what it’s all about. Functional programming can solve many problems more...
After a few months writing Clojure I began writing Javascript again. As I was trying to write something ordinary, I had the following thoughts: They seemed unnecessary. But I imagine I’ve thought…
Functional Programming(FP) can change the way you program for the better. But it’s hard to learn and many posts and tutorials don’t go into details like Monads, Applicative and so on and don’t seem…
