Creating websites that are reactive and responsive used to be considered advanced but responsiveness is a necessity for successful websites and apps. We’ve added media queries, matchMedia, and a host of other APIs to help developers make responsiveness easier and now we get a new one:...
AI-Backed Image Background Removal (Sponsored)
21.5.2019
I’ve worked on dozens of eCommerce sites in my career and many of them were hamstrung by the same pain points: tax collection, payment customization, and image optimization. While tax collection and payment customization were important, image optimization was always the hardest and most...

Footnotes That Work in RSS Readers
17.5.2019
Feedbin is the RSS reader I'm using at the moment. I was reading one of Harry's blog posts on it the other day, and I noticed a nice little interactive touch right inside Feedbin. There was a button-looking element with the number one which, as it turned out, was a footnote. I hovered over it,...
Recursive Array.flat
17.5.2019
There was much talk about Array.prototype.flat during its early stages, starting with the name alone. Many developers preferred the name flatten but the spec differed from MooTools’ implementation. MooTools would recursively flatten an array but the new, official flat implementation was only...
Using Array reduce
14.5.2019
Every developer who specializes in any programming language will tell you there’s a powerful tool the language provides that they rarely use and wish they knew more about. For me, it’s Array.prototype.reduce. I quite enjoy the other Array methods like map, filter, and find, but reduce...
Getting To Know The MutationObserver API
8.5.2019
MutationObserver watches the DOM, specifically the places you tell it to, like:
document.querySelector('#watch-this');
...and it can tell you (trigger a callback) when stuff happens — like when a child is added, removed, changed, or a number of other things.
I used it just the other day...
Type Conversion with JavaScript Arrays
7.5.2019
JavaScript’s loose nature allows developers to employ amazing tricks to do just about anything you’d like. I’ve detailed how you can filter falsy values in arrays using a filter(Boolean) trick, but reader David Hibshman shared another trick for typecasting array values the same...
A Conspiracy to Kill IE6
6.5.2019
Chris Zacharias published a few notes about why the team at YouTube added a banner that asked users to switch from IE6 to a more modern browser back in 2009:
The bittersweet consequence of YouTube’s incredible growth is that so many stories will be lost underneath all of the layers of new paint....
How to Patch Retry System into Super Mario ROMs
6.5.2019
I find myself watching less TV lately and much more time enjoying gamers stream on Twitch. While I too much PUBG, and enjoy watching people like Shroud and ChocoTaco hit bangers, I get more enjoyment out of Grand Poo Bear, Barbarian, and others play ultra difficult Super Mario World ROM hacks....
Awesome Visual Testing with Percy! (Sponsored)
3.5.2019
The more complex the applications I work on, the more I rely on and invest in testing. Whether it’s flow typing, jest tests, unit tests, or selenium tests, I rely on all of them to enforce integrity and save me from myself. One type of testing that’s incredibly important but often...
Flow Object.values(…)
2.5.2019
JavaScript typing utilities, like Flow and TypeScript, have become popular in JavaScript apps of all sizes. As I mentioned in our Script & Style Show typing podcast, typing is a great way to implicitly implement documentation and validation. Flow isn’t always easy to perfect, however,...
Making Web Components for Different Contexts
2.5.2019
This article isn’t about how to build web components. Caleb Williams already wrote a comprehensive guide about that recently. Let’s talk about how to work with them, what to consider when making them, and how to embrace them in your projects.
If you are new to web components, Caleb’s guide is...
Naming things to improve accessibility
2.5.2019
I like the this wrap-up statement from Hidde de Vries:
In modern browsers, our markup becomes an accessibility tree that ultimately informs what our interface looks like to assistive technologies. It doesn’t matter as much whether you’ve written this markup:
in a .html file
in Twig, Handlebars...

Revisiting prefers-reduced-motion, the reduced motion media query

Two years ago, I wrote about prefers-reduced-motion, a media query introduced into Safari 10.1 to help people with vestibular and seizure disorders use the web. The article provided some background about the media query, why it was needed, and how to work with it to avoid creating...
JavaScript Detect Async Function
29.4.2019
JavaScript async/await has changed the landscape of how we code. We’re no longer stuck in callback or then hell, and our code can feel more “top down” again. Async functions require the following syntax: async function myFunction() { } To use await with a function, the function...
