JSJP25|Aapo Alasuutari|Out the cave, off the cliff — data-oriented design in Nova JavaScript engine YouTube video by jsconfjp

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!

Interlude: A data-oriented model · Nova A real-world example of using data-oriented design principles in TypeScript.

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?

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

At JsConf.jp @loading.trynova.dev introduces Andromeda.

Andromeda is a TypeScript-native runtime that uses the Rust-based Nova JS engine together with Oxc.

It aims to be web interoperable and is part of WinterTC.
