Ryan Dahl Asks Oracle to Release the 'JavaScript' Trademark — It's in our small print, but did you know Oracle owns the 'JavaScript' trademark? This is why the standard is called ECMAScript instead. It’s all down to Netscape’s deal with Sun Microsystems, which Oracle later acquired, and is infamously poorly defended (Brendan Eich suggested many years ago that he’s not sure it could be defended.) So if you’ve got Larry Ellison’s phone number, see if he’ll do us all a solid 🙏

An Overview of Node.js's Architecture, Event Loop, and Concurrency — Our favorite JavaScript-wielding doctor is writing a new book (“Writing cross-platform shell scripts with Node.js”) and we get to enjoy the byproducts of his labor including this succinct, but highly technical, overview of Node’s fundamental parts.

Introducing Signals: A Reactive State Primitive That's Fast By Default — Signals provide a reactive way of expressing state (in a very natural way that feels like using plain values) such that apps stay fast regardless of complexity. It’s aimed at Preact, the slimmer alternative to React, but is possible to use with regular React by way of monkeypatching.

The Temporal API: A New Approach to Managing Date and Time? — We’ve mentioned this a few times over the years (Dr. Axel wrote this thorough guide in 2021) but it continues to merely be ‘in development’ with no widespread support yet. There is a polyfill, though, and it really is a handy API, so you might want to brush up on it.

El: A Tiny Web Component-Based UI Framework — The very definition of short and sweet. You get a lot in 150 lines, including a built-in observable store and reactive templates with one-way binding. Think a very lightweight React/Vue mixed with Lit. Here’s a one file example of creating a todo-list app on top of it.
