If you're struggling with long error chains and debugging gnarly bugs, introducing `error.cause` might be worth a try!

allthingssmitty.com/2025/11/10/e...

try {
try {
JSON.parse('{ bad json }');
} catch (err) {
throw new Error('Something went wrong', { cause: err });
}
} catch (err) {
console.error(err.stack);
console.error('Caused by:', err.cause.stack);
}

Did you know that you can localize quotes right in CSS?

Now you do! 🫵

TIL that `dns-prefetch` is now baseline "newly available". I've been using this for ages, but apparently, it only started working in iOS Safari with version 26.

Here are the release notes: webkit.org/blog/17333/w...

dns-prefetch example code: <link rel="dns-prefetch" href="https://fonts.googleapis.com/" />

Quick reminder, if your framework or application requires immutable data structures, `Array.with` will be your friend. It lets you update an item, copies the rest, and provides a new array reference!

It works in all browsers, too! 🎉

Did CSS @scope just hit Firefox Nightly?! 😲 #baselineHereWeCome

Release notes: www.firefox.com/en-US/firefo...

MDN: developer.mozilla.org/en-US/docs/W...

@scope (.article-body) to (figure) {
img {
border: 5px solid black;
background-color: goldenrod;
}
}

The @scope rule is now supported, allowing authors to restrict styling to a subtree of the DOM. This avoids having to write overly-specific selectors.

This is quite a banger feature for web perf engineers. In Chrome Canary, you can now turn on an experimental feature to throttle single requests!

chrome://flags/#devtools-individual-request-throttling

This is golden to check the performance impact of a delayed resource. 👏

The amount of work going into this article is absurd. 👏 Loren has built the same web app in ten frameworks and compared and measured the performance. Why?

To find the most suitable framework for a project.

Man, I love this. Here's a custom element to automatically add side notes to your blog posts. It parses the text, includes feature detection for anchor positioning, and uses progressive enhancement.

This is how things should be done!

meyerweb.com/eric/thought...

class asideNote extends HTMLElement {
connectedCallback() {
if (CSS.supports('bottom','anchor(top)')) {
let marker = document.createElement('sup');
marker.classList.add('asidenote-marker');
this.after(marker);
}
}

Oh nice! Starting with Chrome 142, you can put the bottom drawer to the right side and assign the main panels to it.

For example, it's then possible to look at the Elements and Network panel at the same time.

I think I'll use this a lot! 👏

It seems so rude and careless to make me, a person with thoughts, ideas, humor, contradictions and life experience to read something spit out by the equivalent of a lexical bingo machine because you were too lazy to write it yourself.

Alright, this post is a year old, but it's still a great primer on `AbortController` and how to cancel things in JavaScript.

kettanaito.com/blog/dont-sl...

fetch(url, {

// Abort this request automatically if it takes

// more than 3000ms to complete.

signal: AbortSignal.timeout(3000),

})

I just realized that the new CSS `field-sizing: content` magic allows textareas AND inputs AND select elements to grow. 😲

I thought it was only about textareas. 😅

So far, it works in Chromium and Safari TP.
