State of JavaScript 2023
It should be clear by now that, for better or for worse, JavaScript is not slowing down. Between server components, server actions, signals, compilers, and more, we're seeing new innovations pop up faster than most of us can handle. The trick to avoiding the dreaded JavaScript fatigue is remembering that you can pick your lane: sure, you can live life on the cutting edge with the early adopters; b
Trigonometry in CSS and JavaScript: Introduction to Trigonometry | Codrops
Trigonometry in CSS and JavaScript: Introduction to Trigonometry In this series of articles we’ll get an overview of trigonometry, understand how it can be useful, and delve into some creative applications in CSS and JavaScript. Understanding trigonometry can give us super powers when it comes to creative coding. But to the uninitiated, it can seem a little intimidating. In this 3-part series of a
The problem with new URL(), and how URL.parse() fixes that | Kilian Valkhof
As someone building a browser I need to parse a lot of URLs. Partially to validate them, but also to normalize them or get specific parts out of the URL. The URL API in browsers lets you do that, but it’s ergonomics aren’t ideal. The problem with new URL() The “new” in front of new URL() indicates that it’s used as a constructor: calling it creates a new URL instance for you. When you give it a ma

Using the Popover API for HTML Tooltips May 6, 2024 We looked at the Popover API and how it’s made it’s way across all browsers already just last week.

GitHub - proposal-signals/proposal-signals: A proposal to add signals to JavaScript.
Stage 0 Authors: Rob Eisenberg and Daniel Ehrenberg This document describes an early common direction for signals in JavaScript, similar to the Promises/A+ effort which preceded the Promises standardized by TC39 in ES2015. Try it for yourself, using a polyfill. Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could

I often feel like javascript code in general runs much slower than it could, simply because it’s not optimized properly. Here is a summary of common optimization techniques I’ve found useful. Note that the tradeoff for performance is often readability, so the question of when to go for performance versus readability is a question left to the reader. I’ll also note that talking about optimization n
Positioning anchored popovers
Popovers are commonly positioned relative to their invoker (if they have one). When we use the popover attribute, anchoring is tricky, as these popovers are in the top layer, away from the context of their invoker. What options do we have? Basically, there are two ways to position popovers: one you can use today and one that will be available in the future. I'll detail them below, but first, let's
