I gave a talk at JSConf Japan last month, talking about how #JavaScript objects are put together in mainstream engines and how Nova does something quite radically different, as well as the tradeoffs that implies. Take a look if that sounds interesting! youtu.be/QuJRKhySp-0?...

Oh by the way, I wrote a blog post last week on some #JavaScript #TypeScript work I did at work, where I cut memory usage of an acyclic directed graph 10x in aggregate, and more like 30x on a per node level. Maybe that's interesting to you as well? trynova.dev/blog/interlu...

worker.postMessageはすぐ理解できたけどself.onmessageに苦戦した。最初のworkerスレッド起動時に受け取りを監視するメソッド呼び出してそれをループさせてんだな。 windowメソッドだからなかなかどこにあるかとメソッドの登録のせいで探すの難しかった

isolateって機構が素晴らしすぎる。

ECMAScript excitement 😉 Congrats to @bridgear.bsky.social @jordan.har.band on advancing Object.keysLength to Stage 2 at TC39 today 🎉 let count = Object.keysLength(o) It counts the string-keyed own properties on an object. This avoids the cost of the intermediate array in Object.keys(o).length

あと const myHeader = new Header(); myHeader.append("key", "value"); // 通常は [["key, value"]...] みたいになってる console.log(myHeader) // { key: "value" } みたいな処理はconsole.log内で配列をオブジェクトに変換する処理頑張って書いてて面白かった
