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.

I'm trying out streaming my programming of Nova #JavaScript engine, come watch if you're interested in data-oriented design, bytecode compilers/interpreters, or #Rustlang in general.

@aapoalas.trynova.dev / Nova #JavaScript engine has received funding from NLnet's NGI Zero fund for developing the engine!

The funding is for bringing the engine closer to full Test262 compliance, and for developing the data-oriented heap design and proving its worth. Exciting times ahead!

We found a bug in v8 while developing the @trynova.dev JavaScript engine. I was implementing the Number.prototype.toString method when @aapoalas.trynova.dev found that v8 doesn't properly handle Number.MAX_VALUE.toString()!

I have baked mokkapalat (Swedish originated brownie-like dessert) for tomorrow's team meeting: I am thus fully ready to start my half year leave of absence after Friday.

Full-time focus on @trynova.dev Nova JavaScript engine, here I come!

I think every designer should write a love letter to a font at least once in their lifetime.

This is mine: A 150-year-old font you have likely never heard of, and one you probably saw earlier today.

The year is ending, and Nova JavaScript engine has gone from rags to fairly nice rags during this year. It's time to look backwards and forwards!

Day five of Advent of Code 2024 using the @trynova.dev engine! Not entirely satisfied with my solution as it has a bunch of extraneous loops inside loops making it's Big-O at least O(N^3) and quite slow in the unoptimized engine.

Fourth day of Advent of Code 2024 completed a day late using the experimental @trynova.dev ECMAScript engine! My rather stupid search was quite slow so took about ~5 seconds find all of the matches. ⛄

Hello world! We're a newish JavaScript engine written in Rust with an unconventional heap data structure and layout. We're not quite yet at the 50% conformance rate but we're getting there.

Third day of Advent of Code 2024 done using the experimental Nova ECMAScript engine!
Today only RegExp was missing, a feature I *won't* be implementing anytime soon or else I might just loose what little I have left of my sanity.

Only thing which wasn't implemented yet which I would have wanted to use was `toSpliced`, guess I know what I will be contributing to Nova next! 🎅
