    I've updated the js-framework-benchmark's µhtml version, from 1.X to 2.X: * it moved up 8 places * it's faster than svelte 🥳 table: uhtml:

    1. create a component standard 2. oops, it doesn't work without JS 3. create declarative shadow DOM 4. oops, embedding CSS in JS is bad 5. create CSS modules 6. oops, CSS modules don't work with declarative shadow DOM 7. create declarative constructible stylesheets 8. oops, ...

    Questions for those familiar with CSS modules script (the native one): in order for the imported stylesheet to take effect, it needs JavaScript to set adoptedStyleSheets. Does this mean that 1. It won't work without JavaScript (i.e. no JS-less SSR) 2. It can't avoid FOUC?

    My feelings about SD since about ever … it was more for embedded ads than anything else, and builtin extends have always been superior for real-world use cases, imho.

    I've been using shadow dom for over a year a half, and I still don't see many real world use cases for it. For most situations it introduces more problems than it solves

    comments in reviews before anyone asks anything are kinda a nice touch, but unfortunately these instantly break my ability to review code top-down and, eventually, ask questions around stuff that needs clarification. is it just me? 🤔

    To give a hint regarding how much in scale this BS exists, the same debate is happening in my FB stream because Tamberi, another gold medal, grew up and lived in my hometown since about ever, but he was just born in a different place. A "war" to claim a champion is *not* sport.

    There are people mad because an Italian that spent the first month of his life in Texas is not technically Italian … that debate is far more important/relevant than celebrating 100m sport and a new European record. This is what sport means these days, and I don’t even

    I don’t care about, need, or use, TS, but hat tip to all the contributors that land, or help improving, .d.ts files related to my projects. Thank you, you’re awesome 👏

    out of curiosity, as soon as you bought your Apple laptop/working product, have you erased it already to have a case **sensitive** journal in there, like I've always done to date? 🤔

    Almost forgot to mention: no eval/Function needed! The whole logic is based on async/await and namespace/instance crawling. Worker namespace is read-only, and one can await anything in it, including new classes.

    The FinalizationRegistry API is not strictly related to the WeakRef one. It allows handling remote instances, a worker, through Proxies, w/out leaking memory. My recent proxied-worker module is a successful experiment in this area: lot of potentials 👍

    TFW after few days on Rust you involuntarily start writing: new Promise((Ok, Err) => { ... }) instead of the usual new Promise((resolve, reject) => { ... }) 🤷

    SQLite is one of those WASM that needs such CSP rule, at least in Web Extensions, otherwise Chrome refuses to make it work. That rule throws in Firefox manifest though. As side note, sqlite-worker got an update: raw helper in workers too 🥳

    "script-src 'self' 'wasm-eval'; object-src 'self'" if WASM requires dynamic heap allocation, this CSP rule is required in Chrome, but Firefox is not compatible with it, + it doesn't care. my recent conclusion is that WASM is awesome, yet too young to be *the bet* in prod, imho.

    I mean ... yeah, we can all blame JS for breaking there, but if a site has so much wrong JS on the Front End, do we really expect it to have super skilled Back End developers? I don't think so ... but I am sure they complain when any user is "lost in transaction" 🤷‍♂️ 😢

    TIL: in Italy there are companies that make sites that don't work on Firefox, and likely won't work in Chrome neither. Form emails normalization where they capitalize Each@Email.Com, awkward cell phones input ruined by awkward JS ... the issue is not JS per se, it's incompetence!

    TFW you just push few lines of code during lunch, and people star it already ... vanilla-elements is a "vaporware" helper to simplify Custom Elements definition, through a `define(name, Class)` signature that works with builtin extends too. it's up 👍
