New kid on the block
The world of front end frameworks is always evolving. For years it was dominated by jQuery and Backbone, but these days we hear most talk about React and Vue. However, there is another framework that hasn't been talked about so much, namely Svelte. Although this framework is actually three years old, it had a rebirth in April this year with the release of its third major version.

Cellular Automata in the Browser
A short recap on polyfills
Maybe you’ve heard of Fetch? The promise-based Web API for making network requests in the browser, and a favourite amongst developers. If you paste fetch(‘https://www.google.com’) into the Chrome DevTools console and run it you can take a closer look at how it works. Sadly, you can’t do the same in Internet Explorer. It won’t work. That is because Internet Explorer has not implemented support for Fetch. Or Promise for that matter.

A symbolic gift
Years ago, the JavaScript language was gifted with the Symbol primitive. Unlike many other language features in ES6, it was not simply a shorter syntax for doing something otherwise previously possible. It is not obvious what the point of these symbols are, and they are not commonly used. If you try to read up on them, you will find that many articles focus on details that are not important to the purpose of symbols. This article will explain what they are, what the point is, and give some real life use cases.

The Magic of TypeScript
I like TypeScript. I also like Magic the Gathering. What if we combine them; can the magical domain of planeswalkers and spells help us understand the awesome but advanced type system of TypeScript?

Writing JavaScript With Only Six Characters
You've probably seen someone on the internet write funny-looking but runnable JavaScript code using only six different characters. But how does that actually work?

Hoisting
If you are new to JavaScript, chances are that you might find it a bit confusing at times. This is with good reason as JavaScript is a language of many quirks packed with odd behaviors and inconsistency. Let's make JavaScript a bit less confusing by tackling one of the more overlooked quirk of JavaScript known as Hoisting.

Feature toggling as a service – ❤️at first sight
I used to think that feature switches were clunky if-statements in my code that would require re-compilation or at least restart of my app. Launch Darkly proved me totally wrong, swinging me from cynical scepticism to deep love!

The Adaptive Web Developer
Modern frameworks are easy to learn. From zero web experience, they help you get productive in a matter of weeks. But for me, the web remained a mystery until I taught myself the very basics.

Should you choose npm or yarn?
Every team has to make various decisions before, and during, the development of a digital product. One of these usually involves yarn, npm or another tool to build and package javascript code. Some developers have a burning desire to go in a certain direction, and sometimes they end up spending a considerable amount of time trying to make decisions that in fact will have little impact in their everyday life.
