This guide will use JavaScript instead of a pure functional programming language (e.g. Haskell) to make things more approachable for developers accustomed to imperative languages. It will, however, assume you have basic knowledge of functional programming, including currying and lambdas.
A JSON alternative that retains references, handles circular dependencies, and encodes almost every data type available to standard JavaScript. - cierelabs/json-complete
This guide is intended to catch you up with the state of JavaScript testing in 2019. It combines information from the best recent articles, and our own experience at Welldone Software Solutions.
ECMAScript 2019 has landed! It's time to look what's new and... go beyond that! ECMA-262 and ECMAScript 2019 release cycle, features, proposals and more!
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.
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.
In Practical guide to writing more functional Javascript, we walked through how to reason about our code in functional programming terms. In this guide, we will talk about a few utilities I like to use to reason about these concepts and help us navigate through the imperative constructs JavaScript natively provides.
Svelte is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app.
Functional programming is a great discipline to learn and apply when writing JavaScript. Writing stateless, idempotent, side-effect free code really does solve a lot of problems: But there’s a…
Reactive paradigm is a declarative way to manage changes in application status (versus traditional imperative programming), based on the concept of event streams.
As functional programmers, we like to piece our programs together out of small pieces. Our main tool for this is composition. We take an input, process it through a function, then pass it on to another function. And this all works great so long as all our functions take exactly one argument. Which never happens. So what do we do? In general, we turn to a set of tools called combinators. This article focusses on a particular combinator called the blackbird.
JSON itself does not specify how dates should be represented, but JavaScript does.
You should use the format emitted by Date's toJSON method:

This is part of a three part examining the underling mathematics and mechanics of Asynchronous programming with javascript When i wanted to make sense of the continuations , i started from the basics…
Markdeep is a technology for writing plain text documents that will look good in any web browser, whether local or remote. It supports diagrams, calendars, equations, and other features as extensions of Markdown syntax.
I thought it would be fun to use Stefan Krause’s benchmark tool to, only for the sake of competition, do some performance comparison between the most well-known front-end frameworks and UI libraries…
Immutability is changing - time for an exploration of why Immer is a philosophical fit with React! Why has Immer gained so much love this year, and does it have staying power?
Modals, there are a thousand ways of implementing them, but the biggest challenge is to keep them simple and flexible. Let’s do that with React Hooks and Portals!
JSbooks is a showcase of the bests free ebooks about Javascript. Find here the best publications about your favourite programming langage without spending any bucks !
React Hooks API is officially released in React 16.8.In this post, we focus especially on useReducer by introducing various use cases. Before continuing reading this tutorial, please read the…
TypeScript grew a great deal between 2017 and 2019, and in many ways, for good reason. There’s a lot to love about TypeScript. In the 2018 State of JavaScript survey, almost half the respondents said…
A project to move the JavaScript ecosystem forward.. Search npm for fast, small, and modern web packages.Our catalog only includes packages that are built with modern ESM syntax and a package.json 'module' entrypoint.
When webpack bundles your javascript it wraps all of your individual files/modules in functions so they are no longer run in the global scope, therefore if you want to make a variable global you have to explicitly set it on the window object, i.e.
window.a = 1;
