idk if folks at @boajs.dev monitor this, but here it is:

inspired by ryu-js -- here's zmij-js, based on the new cool kid in the block (faster floating point formatting because we love microbenchmark wins)

Haven't poked at porting `.toFixed` stuff yet, but it's alive!

AIにECMA-376ベースで自力解析自力構成しろと指示するようになってから、ExcelもExcel方眼紙も嫌いじゃないというかむしろ優れてると思うようになりました。
とくに老害の象徴とされてきたExcel方眼紙。今情報をAIに食わせようとOffice文書やPDFを必死でMarkdown等の構造化テキストに変換してる人いますけど、見た目の配置と意味上の構造をリンクさせ、人の意図を機械に伝える土台作りという点でExcel方眼紙は30年先を行ってた

In a way even c uses js & ecma under the hood. It's a bit slow & a lot is missing but that hasn't been my focus yet. The idea is even c programs run in a sandbox w/ secure capabilities. Imagine a stable platform, a bit like jvm but for all languages

I was being silly, but JSON was published as RFC 4627 long before ECMA-404.
RFC authors don't choose licenses, there's some IETF license that applies to all of them.

json2.js and json-sans-eval.js, used to parse/unparse JSON before JS standardization, both have public domain headers.

2M lines of #code later vybe #wasm #compiler up from 50% of 10K tests pass to 90% of 110K. More compliant w/ WASM/ECMA, the idea: show #coding languages can share 1 runtime: call powershell from bash/cobol from fortran, only way to run vb winform on mac (probably linux).

Yes, it 100% is, as well as the experience economy. Thank me later.

I did. It is not compelling. You have fundamentally failed to understand the power law nature of this sector.

Please read the ECMA article I referenced and the technical note that works out the math, if you'd like to engage more. (no, the attention economy is not "echoed" in the relational economy).

Yes that’s what I also used, but for example compare:

tc39.es/ecma262/mult...

And

eel.is/c%2B%2Bdraft...

The C++ multipage spec has smaller pages (therefore easier to consume and navigate), anchored directly by expr.static.cast and using the paragraph number it’s easy to locate.
