TypeScript, Minus TypeScript
6.8.2020
Unless you’ve been hiding under a rock the last several years (and let’s face it, hiding under a rock sometimes feels like the right thing to do), you’ve probably heard of and likely used TypeScript. TypeScript is a syntactical superset of JavaScript that adds — as its name suggests — typing to...
Match Accented Letters with Regular Expressions
6.8.2020
Regular expressions are used for a variety of tasks but the one I see most often is input validation. Names, dates, numbers…we tend to use regular expressions for everything, even when we probably shouldn’t. The most common syntax for checking alphabetic characters is A-z but what...
Expanding the Future (of Dev Tooling) with AI
5.8.2020
Codota wants their tools to (at least!) double developer productivity. My vision is that we can do that not only by getting more developers using these tools, but in expanding where and how these tools learn themselves. The better the tools can *learn from us* what we're doing, the better *we...
Promise.allSettled
3.8.2020
The Promise object has many useful functions like all, resolve, reject, and race — stuff we use all the time. One function that many don’t know about is Promise.allSettled, a function that fires when all promises in an array are settled, regardless of whether any of the promises...
A Lightweight Masonry Solution
31.7.2020
Back in May, I learned about Firefox adding masonry to CSS grid. Masonry layouts are something I’ve been wanting to do on my own from scratch for a very long time, but have never known where to start. So, naturally, I checked the demo and then I had a lightbulb moment when I understood...

Vue 3.0 has entered Release Candidate stage!
23.7.2020
Vue is in the process of a complete overhaul that rebuilds the popular JavaScript framework from the ground up. This has been going on the last couple of years and, at long last, the API and implementation of Vue 3 core are now stabilize. This is exciting for a number of reasons:
Vue 3 promises...
WordPress-Powered Landing Pages on a Totally Different Site via Cloudflare Workers
22.7.2020
What if you have some content on one site and want to display that content on another site? We can do this in the browser no problem. We can fetch it, and plunk it onto the page.
Ajax, right? Ugh. Now we’re in client-side rendered site territory, which isn’t great for performance...
What ya need there is a bit of templating
22.7.2020
I had a fella write in to me the other day. He had some HTML, CSS, and JavaScript, and it just wasn’t behaving like he thought it ought to. The HTML had some placeholders in it and the JavaScript had some data in it, and the assumption was that the data would fill the placeholders.
To those...
How to Make a Monthly Calendar With Real Data
21.7.2020
Have you ever seen a calendar on a webpage and thought, how the heck did they did that? For something like that, it might be natural to reach for a plugin, or even an embedded Google Calendar, but it’s actually a lot more straightforward to make one than you might think and only requires...
Binding Arguments with Bind
20.7.2020
One of my favorite and most essential Function method is bind, a function we added to MooTools when it wasn’t featured in the JavaScript language itself. We often think of using bind to simply bind a method’s call to its host object, but did you know you can also bind arguments with...
Creating a Gatsby Site with WordPress Data
20.7.2020
In my previous article last week, I mentioned creating a partially ported WordPress-Gatsby site. This article is a continuation with a step-by-step walkthrough under the hood.
Gatsby, a React-based framework for static sites, is attracting attention not only from JavaScript developers but also from...
Netlify Does Cache Invalidation For You
15.7.2020
This is one of my favorite Netlify features. Say you’re working on a site and you change as asset like a CSS, JavaScript, or image file. Ya know, like do our job. On Netlify, you don’t have to think about how that’s going to play out with deployment, browsers, and cache. Netlify...
Three CSS Alternatives to JavaScript Navigation
14.7.2020
Hey quick! You’ve gotta create the navigation for the site and you start working on the mobile behavior. What pattern do you choose? If you’re like most folks, it’s probably the “hamburger” menu that, when clicked, uses a little JavaScript to expand a vertical list of navigation links.
But that’s...
Lazy Load IFRAMEs
13.7.2020
We’ve known for a decade that lazy loading resources like JavaScript, CSS, and especially images is a massive performance win for web pages. At first we used tricks and JavaScript to do the lazy loading, but more recently native image lazy loading has debuted in browsers. Did you know that...
We need more inclusive web performance metrics
10.7.2020
Scott Jehl argues that performance metrics such as First Contentful Paint and Largest Contentful Paint don’t really capture the full picture of everyone’s experience with websites:
These metrics are often touted as measures of usability or meaning, but they are not necessarily meaningful...

A new Javascript library for Liquid could allow external developers to build a complete ecosystem around the heavily upgraded Bitcoin sidechain
A little bit of plain Javascript can do a lot
8.7.2020
Julia Evans:
I decided to implement almost all of the UI by just adding & removing CSS classes, and using CSS transitions if I want to animate a transition.
An awful lot of the JavaScript on sites (that aren’t otherwise entirely constructed from JavaScript) is click the thing...
How to Make a List Component with Emotion
8.7.2020
I’ve been doing a bit of refactoring this week at Sentry and I noticed that we didn’t have a generic List component that we could use across projects and features. So, I started one, but here’s the rub: we style things at Sentry using Emotion, which I have only passing experience with and...
Displaying the Current Step with CSS Counters
8.7.2020
Say you have five buttons. Each button is a step. If you click on the fourth button, you’re on step 4 of 5, and you want to display that.
This kind of counting and displaying could be hard-coded, but that’s no fun. JavaScript could do this job as well. But CSS? Hmmmm. Can it? CSS...
