How to Animate the Details Element Using WAAPI
5.11.2020
Animating accordions in JavaScript has been one of the most asked animations on websites. Fun fact: jQuery’s slideDown() function was already available in the first version in 2011.
In this article, we will see how you can animate the native <details> element using the Web Animations...
Additive Animations in CSS
3.11.2020
Daniel C. Wilson explains how with CSS @keyframe animations, when multiple of them are applied to an element, they do both work. But if any properties are repeated, only the last one works. They override each other. I’ve seen this limitation overcome by applying keyframes to nested elements...
Limit Promise Concurrency with pool
3.11.2020
Methods like Promise.all, Promise.allSettled, Promise.race, and the rest are really excellent for managing multiple Promises, allowing for our apps to embrace async and performance. There are times, however, that limiting the number of concurrent operations may be useful, like rate limiting...

Smarter Ways to Generate a Deep Nested HTML Structure
21.10.2020
Let’s say we want to have the following HTML structure:
<div class='boo'<div class='boo'<div class='boo'<div class='boo'<div class='boo'</div</div</div</div</div
That’s real a pain to write manually. And the reason why this post was born was being...
“Durable”
20.10.2020
Looks like the word “durable” is an emerging term in the world of serverless. As I understand it, it’s like allowing for state in places you wouldn’t normally expect to have it. For example, you call some cloud function and run some JavaScript… unless you have it...
cookieStore: Async Cookie API
20.10.2020
One pattern in the JavaScript API world that web development veterans will notice is that we’ve been creating new methods to accomplish what older, grosser APIs once achieved. XMLHttpRequest became the fetch API, some APIs like Battery became async, and there are dozens of other examples....
How to Prevent Pasting into an Input
19.10.2020
Every once in a while I get to a website that doesn’t allow me to paste into a form input. In most cases it’s something to do with login credentials (username and or password) and auth codes. So how are they preventing me from pasting information? It’s as easy as you’d...
How to Conditionally Add Attributes to Objects
16.10.2020
JavaScript is full of tricks that you don’t know you want until you … want … them. Or maybe just until you see them. One trick I recently realized was conditionally adding attributes to React elements. Of course this trick essentially boils down to conditionally adding properties...
Ryan stvořil Deno a bylo to dobré
15.10.2020
S nadsázkou se dá prohlásit, že vzniku Deno vděčíme hryzavému svědomí Ryana Dahla, autora NodeJS. Za jedenáct let, které dělí první verzi NodeJS a první verzi Deno, se ve světě referenčního JavaScriptu událo mnohé. Následovník NodeJS je proto mnohými vítán
Netlify Edge Handlers
13.10.2020
Some very cool news from Netlify: Edge Handlers are in Early Access (request it here). I think these couple of lines of code do a great job in explaining what an Edge Handler is:
export function onRequest(event) {
console.log(`Incoming request for ${event.request.url}`);

How to Recreate the Ripple Effect of Material Design Buttons
12.10.2020
When I first discovered Material Design, I was particularly inspired by its button component. It uses a ripple effect to give users feedback in a simple, elegant way.
How does this effect work? Material Design’s buttons don’t just sport a neat ripple animation, but the animation also...
Using JavaScript to Adjust Saturation and Brightness of RGB Colors
6.10.2020
Lately I’ve been taking a look into designing with color (or “colour” as we spell it where I’m from in New Zealand). Looking at Adam Wathan and Steve Schroger’s advice on the subject, we find that we’re going to need more than just five nice looking hex codes from a color palette...
How to Detect When a Sticky Element Gets Pinned
5.10.2020
The need for position: sticky was around for years before it was implemented natively, and I can boast that I implemented it with JavaScript and scroll events for ages. Eventually we got position: sticky, and it works well from a visual perspective, but I wondered how can we determine when...
The Paper Prototype Rule

I’ve been lucky to have worked with some of the best designers in the industry, including Zhenya Rynzhuk, Louis Paquet, Maria de la Paz Vargas, and of course, dozens of the amazing designers at MediaMonks. Many of the projects we’ve worked on require custom animation and guidelines that enable...
The Flavors of Object-Oriented Programming (in JavaScript)
28.9.2020
In my research, I've found there are four approaches to Object-Oriented Programming in JavaScript. Which methods should I use? Which one is "the best" way? Here I'll present my findings along with information that may help you decide which is right for you.
The post The Flavors of Object-Oriented...
Web Technologies and Syntax
24.9.2020
JavaScript has a (newish) feature called optional chaining. Say I have code like:
const name = Data.person.name;
If person happens to not exist on Data, I’m going to get a hard, show-stopping error. With optional chaining, I can write:
const name = Data.person?.name;
Now if person...
How to Create an Async Function
24.9.2020
One thing I love about JavaScript is that there are many ways to accomplish the same task, one such example being creating functions. There are several patterns for functions; one of the last you see used is the new Function method: /* new Function(arg1, arg2 (...), body) */ const myFunction =...

Thinking About Power Usage and Websites
22.9.2020
Gerry McGovern asked if I had any insight into energy consumption and websites. He has a book, after all, about the digital costs on the planet. He was wondering about the specifics of web tech, like…
If you do this in HTML it will consume 3× energy but if you do it in JavaScript it will...
