Oxlint: A New JS Linter ’50-100x Faster’ than ESLint? — Making tools as fast as possible is a common theme in the JavaScript world, and it’s the MO for the JavaScript Oxidation Compiler toolkit. Oxlint is one of their tools that’s now GA. It’s still early days, but when Evan You says “the performance is absolutely nuts” when running against the Vue 3 codebase, we sit up and listen.


Bun v1.0.18: The JS Runtime Preparing to Take Over the World — I might have overegged the headline, but Bun is on a serious mission to replace Node.js, at least, with their ‘one goal for 2024’ being to “flip the default backend JavaScript runtime from Node.js to Bun.” They are also placing a focus on shipping Windows support ASAP.

Visual Studio Code November 2023 — The latest VS Code release has some handy enhancements for JS developers, including a V8 heap snapshot visualizer, the ability to drag tabs into their own new windows (a.k.a. ‘floating editor windows’), and TypeScript 5.3.


Deno 1.39: The Return of WebGPU — Deno introduced WebGPU support in Deno 1.8 but it was removed for various reasons. It’s back and gives you a tidy way to work with the GPU directly from JavaScript (behind the –unstable-webgpu flag, at least). Improvements to Node.js compatibility and various Deno APIs, as well as TypeScript 5.3, are included.

RE:DOM 4.0: The 2K UI Library — We first linked to this library over 6 years ago but it’s still going, so if you want something to help with creating and syncing DOM elements that’s ‘close to the metal’, it’s worth a look. v4.0 enables tree shaking and adds viewFactory.
