The introduction to Reactive Programming you've been missing
The introduction to Reactive Programming you've been missing (by @andrestaltz) This tutorial as a series of videos If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming. So you're curious in learning this new thing called Reactive Programming, particularly its varia
The Essence of FRP
Conal Elliott proposed functional reactive programming twenty years ago with a clear denotational semantics. Over time the idea gained popularity but the original conception became blurred. In this video Conal explains FRP’s original formulation and its benefits. Slides are available here. Summary FRP is is receiving more interest now but has become misunderstood The notion of FRP was very precise

Reflex FRP
Reflex adapts to changes in your...DataReflex apps automatically react to changing data. This keeps every interaction current, accurately representing the relationship between your data and the real world. Reflex is the key to writing self-updating user interfaces. RequirementsReflex components are modular and reusable. If your requirements change, your app can quickly and easily be reworked. The
Modulz
Almost all design tools are optimised for illustration. Drawing tools are great for exploration but when it comes to designing websites, apps, and user interfaces, we need something more powerful. Modulz is optimised for designing digital products and design systems. "It is exceptionally hard to have a great design tool that outputs useful code. Many have tried but in the end the trade offs were t
Eta Programming Language - Haskell on the JVM
What is Eta? Eta is a pure, lazy, strongly typed functional programming language on the JVM. It brings two big ecosystems, the JVM and Haskell, together. This allows you to harness the best of both ecosystems to build your applications quickly and effectively. Eta's concurrency support helps you to build highly scalable systems.
fast-check - Property based testing for JavaScript and TypeScript
Property based testing is another way to test programs. Instead of relying on hard-coded inputs and outputs, it checks characteristics of the output given the whole range of possible inputs. Coverage more > By nature, property based testing puts less constraints on the inputs. As a consequence, the scope of covered inputs is much higher and can lead to unexplored code paths
Multithreading Rust and Wasm
When WebAssembly was first shipped it was an MVP which, while minimal, has spawned a huge number of exciting projects which work today across all major browsers. Rust has capitalized on the wasm MVP’s success as well with tools like wasm-bindgen and wasm-pack by making the MVP feel less minimal. WebAssembly is yet more ambitious, though! Since inception it’s always been intended to extend the WebA
Introduction - Rust and WebAssembly
Rust 🦀 and WebAssembly 🕸 This small book describes how to use Rust and WebAssembly together. Who is this book for? This book is for anyone interested in compiling Rust to WebAssembly for fast, reliable code on the Web. You should know some Rust, and be familiar with JavaScript, HTML, and CSS. You don't need to be an expert in any of them. Don't know Rust yet? Start with The Rust Programming Lang
RustのHigher-Kinded type Trait | κeenのHappy Hacκing Blog
κeenです。少し前の話になりますがRustの関連型を駆使してHigher Kinded type Trait（高階型トレイト）を実現してしまったものが出回ってたのでそれについて。 本来RustはHKTをサポートしていませんが不思議なことに実装出来てしまっているのです。 HKTについて微塵も知らない方にも分かるように解説していきます。 map 可能なトレイト Option、Result、etc 色々なトレイトが map メソッドを実装しています。 それぞれ型シグネチャを抜き出してみましょう。 Option: map<U, F: FnOnce(T) -> U>(self, f: F) -> Option<U> Result: map<U, F: FnOnce(T) -> U>(self, op: F) -> Result<U, E> 驚く程似てますね。これを抽象化して「mapメソッドを持つ」
