Object.assign() is... alright, but it's really weird that there's no #JavaScript Object.merge() so that merging { a: 1, b: { c: 3}} and { b: { d: 4 }} becomes { a: 1, b: { c: 3, d: 4 }} instead of just blind-overwriting "b".

Sadly, this idea doesn't seem to translate to wasm, but that's probably because V8 doesn't generate the most efficient instructions for a combo of __builtin_ctz and wasm_i8x16_bitmask.

Ideally it should use “vshrn” as per this article community.arm.com/arm-communit

Do I still know anyone on the V8 team who can help me implement this? (Boosts for reach appreciated)

community.arm.comPorting x86 vector bitmask optimizations to Arm NEONArm NEON is different from x86 SSE in many ways. In this blog, Google's engineer Danila Kutenin shows how to translate popular x86 vector bitmask optimizations to Arm while retaining high performance, resulting in significant improvements across various major libraries like zstd.

There are a number of useful little functions in node:util besides util.inspect() that I’m only just familiarising myself with after admittedly rolling my own versions for a number of them. Hmm, should’ve read through this documentation page more carefully sooner.

e.g., util.deprecate(), util.diff(), util.debugLog(), util.isDeepStrictEqual(), etc.

New Kitten release

• Fixes #236¹: The data preview pages in Kitten’s settings how handle circular references in the deserialised data (which may contain your custom classes if that’s what you were persisting in the database).

kitten.small-web.org

:kitten:💕

PS. Those pages are very rudimentary at the moment and are good for getting quick visual overview of the data you’re persisting. For a fully interactive view, use Kitten’s interactive shell (REPL)² to explore your data until I’ve had a chance to implement a more comprehensive visual interface.

PPS. You persist data in Kitten using the built-in JavaScript Database (JSDB)³ (Or, of course, you can install and use any other database.)

This minimalist static site generator pattern is only for #JavaScript developers who want something small, fast, flexible, and comprehensible jan.miksovsky.com/posts/2025/0

Configuring a complex tool can take more work that just coding the functionality from scratch. Earlier I created a simple blog in #Astro, a popular #SSG. That felt more complicated than the problem justified, so I rewrote the entire #blogging project from scratch in pure JavaScript with 0 dependencies.

This went very well!

JSX-Syntax with Webcomponents.

positive-intentions.com/blog/d

I made something to try out and I'm working towards a UI framework for my personal projects. It's far from finished but perhaps this might be interesting to share.

positive-intentions.com · Dim: Functional Web Components | positive-intentionsModern JavaScript frameworks like React JS and Vue JS have popularized the functional programming paradigm and declarative approaches to web app development. While these frameworks have made creating dynamic web applications more accessible, it's worth exploring the potential of web components in this landscape. Lit elements, with its minimalistic and declarative approach, stands out as an appealing base for leveraging web components in modern web and app development.
