Enable ES modules in Node today with a new opt-in, spec-compliant, ECMAScript (ES) module loader that enables a smooth transition between Node and ES module formats with near built-in performance!
One of the new features introduced in the ES6 standard is the Proxy object. The Proxy object is used to define custom behavior for fundamental operations (e.g. property lookup, assignment…
Like many hackers, my first real programming language love was Lisp. Paul Graham, who inspired my own explorations of the language, is a particular advocate and has written quite a bit about Lisp and…
JavaScript’s dynamic nature, first-class functions and prototypes could always be used for elegant metaprogramming. Proxies let programmers further blur the line between the native, user defined objects and the host objects.
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.
Two weeks ago at EmberConf, we announced Glimmer.js, a component-based library for writing superfast web applications. In the demo video, we use TypeScript to write our Glimmer components. Some…
It has come time to read the liner notes and write some conclusions. When we started writing this blog series, we knew that JavaScript/web application frameworks were not easy to summarize.
In 2016 React cemented its position as king of the Javascript web frameworks. This year saw rapid growth of both its web and native mobile libraries, and a comfortable lead over main rival Angular…
This lesson shows what can be learned next as a continuation of this course, and gives a recap on the core concepts: main for pure logic, drivers for side effects, run() to connect main and drivers, sources for read effects, sinks for write effects, and nesting Cycle.js apps to work as components.
Continuing on from my previous article Want to learn JavaScript in 2015 / 2016. I’m going to walk you through what else I’ve been up to in the world of Javascript. Initially I’d planned to talk about…
There’s one question that comes up again and again on stackoverflow. The question is about ngDoCheck lifecycle hook that is triggered for a component that implements OnPush change detection strategy…
In the last couple of years there has been an explosion in JavaScript frameworks. How is a developer or business to make a wise choice? What are the advantages, trade-offs and differences? In this talk we’ll compare and contrast six popular front-end frameworks: Angular 1, Angular 2, Polymer, React, Ember and Aurelia.
Mithril is a modern client-side Javascript framework for building Single Page Applications. It's small (< 8kb gzip), fast and provides routing and XHR utilities out of the box.
Web components are made up of 4 separate specs, custom elements, shadow DOM, HTML imports, and the template tag. For the purposes of this article we will focus specifically on custom elements.
An updated list of sites that offer free public domain books (ebooks and audiobooks) that you can download and use legally. Project Gutenberg, Europeana, DPLA, Internet Archive, Feedbooks, Open Library, and more.
I recently wrote an article called “Master the JavaScript Interview: What’s the Difference Between Class and Prototypal Inheritance?” Afterwards, I got several questions asking for more information…
Always write code that can be maintained by anyone who may end up working on your software. To that end, here are several programming principles to help you clean up your act.
In a previous article, I introduced a neat little pattern I use to leverage Promise.then() so that I can compose both synchronous and asynchronous functions together into a sort of sequential…
I'm going to share with you common pitfalls when learning to program (or mastering programming). Many of these affect both beginners and professionals.
Created by Jay Phelps and myself for use on our projects at Netflix, redux-observable is middleware for redux that is inspired by redux-thunk. redux-observable allows developers to dispatch a…
Today, we are are going to talk about composition over inheritance. Inheritance is when you design your types after what they are, while composition is when you design your types after what they…
The popularity of TypeScript has really exploded recently. I like TypeScript, and I like static types. I don’t use TypeScript, but as type systems go, it’s got some great features. It’s structural…
Golang is a programming language you might have heard about a lot during the last couple years. Even though it was created back in 2009, it has started to gain popularity only in recent years…
I googled test patterns in Go, then I invoked the Spirits of the Core Library. As soon as I realised where to look at, I finally saw a sign. It was Brad Fitzpatrick.

A double pack: - Jasper talks about Getting things done in Haskell (adapted from his 2017 Haskell eXchange talk ) - Simon and Jasper talk about organizing th...
Determining what this is is actually rather simple. The overarching rule is that this is determined at the time a function is invoked by inspecting where it’s called, its call site. It follows these…
One simple reason. JavaScript has two visually similar, yet very different, ways of testing equality. This is your high level overview of the differences.
Hoogle is a Haskell API search engine, which allows you to search many standard Haskell libraries by either function name, or by approximate type signature.
In Javascript understanding functional programming is becoming a necessity to quickly on-board and become productive thanks to React and Flux. But with Monad and Setoid groups, being able to grok FP…
We would like to use the Coq proof assistant to mechanically verify properties of Haskell programs. To that end,we present a tool, named hs-to-coq, that translates total Haskell programs into Coq programs via a shallow embedding.
The great thing about this course is that it also aligns with the Basic JavaScript Challenges on the beta freeCodeCamp curriculum. You can practice what you're learning through the videos using the…
I’m an ancient web developer who is learning modern JavaScript. I’ve just gotten started and I’m having a ball, but I’ve also got whiplash. There are a few things I wish I’d understood and accepted about the world of modern JavaScript before I got started. Here are some of the changes I had to make to my own mindset and expectations around learning a new ecosystem based on an old language which has taken over my craft.
JavaScript seems to be everywhere, but is it really taking over? This article reviews the different flavors of JavaScript, focusing on how the differ and what it means to developers.
I think in the coming years we’ll see less vanilla JavaScript being written, and more compilation into JavaScript from different sources for the web platform.
In case you missed it, Node now supports async/await out of the box since version 7.6. If you haven’t tried it yet, here are a bunch of reasons with examples why you should adopt it immediately and…
Douglas Crockford is known as The JavaScript Guy. He’s famous not only for his O’Reilly book JavaScript: The Good Parts but even more so as the visionary beh...
